Re: s-function in SPSS curve estimation
On Thu, 20 Dec 2001, Johannes Hartig wrote: Does anyone know the original applications or the meaning of the S-function in SPSS? I know the function itself: Y = e**(b0 + (b1/t)) or ln(Y) = b0 + (b1/t) and I know how the curve looks like, but I am wondering in which fields of research this function is typically used and which empirical relations it describes? You may find it looks a little more like other functions you have seen somewhere if you rewrite it as Y = a*e**(b1), or equivalently ln(Y) = ln(a) + b1 When it is desired to find the value of a, it is simply e**(b0), from your equation above. In biological contexts, this describes an exponential growth curve (which applies to some period of almost any organism's life, usually its extreme youth, before environmental constraints restrict its growth rate). Then the parameter b1 is positive and is intimately connected to doubling time, the length of time during which the organism doubles in size. I suspect that this is why your original formulation had b1/t in the exponent. If b1 is negative, then the equation models exponential decay, and the parameter b1 is connected (in exactly the same way as above) to half-life. Applications include (perhaps obviously) the diminution over time of the radioactivity of a radioactive substance. - DFB. Donald F.

There will have been a variable named zread created by the COMPUTE/EXECUTE sequence and stored in the active data file, but if you have not asked for output you won't get any.

Re: Comparing Software Options-NCSS, Minitab, SPSS
I am a MINITAB user and don't claim to have used it with the sample sizes your talking about. BUT, I would venture to say that it has the best reliability analysis tools of any general statistics package out there. Only Weibull ++ and (maybe) WeibullSmith are better. By "reliability analysis" I'm referring to nonparametric and parametric analysis of censored data. If that is the type of survival analysis you are wanting to do, you might call Minitab Inc. to see how MINITAB will handle the sample sizes you have. By the way, you can download a FULL working copy of MINITAB 13 from their website and try for yourself - http://www.minitab.com .The only catch is the software stops functioning after 30 days. I think MINIAB will be more expensive than NCSS, so if NCSS has the analytical tools you need it may be a better choice. If you'll be using the tool for a long time (not just a one time analysis) I suggest you get demos of all of them and see for yourself which meets your needs. Its the only sure way to tell. Ken "Robert Ehrlich" [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]... I vote for NCSS with hard copy manuals (they are worth it). The maximum number of samples that we have input to NCSS is around 500,000 and it still ran albeit very slowly (I was using the time series procedure). all of your potential choices are OK.

Speaking of ANOVA in SPSS...
I'm trying to reduce all stats to a few simple procedures that students can do EASILY with available stats packages. A two-way ANOVA or an ANCOVA is as complex as I want to go. I thought SPSS would do the trick, but I was amazed to discover that it can't. Here's the example. I want students to convert repeated-measures data into unpaired t tests or non-repeated measures ANOVA, by using change scores between the time points of interest. That's no problem when there is just the group effect: the analysis becomes a simple unpaired t test. But when you have an extra between-subjects effect (e.g. males and females in the treatment and control groups) it becomes a two-way ANOVA. You make a column of change scores between the time points of interest (e.g., post and pre), and that's your dependent variable. The two independent effects are group (exptal and control, say) and sex (male and female). The group term gives the effect of the treatment averaged for males and females. Again, no problem there, but what I want is an appropriate customized contrast of the interaction term, which yields the difference in the overall effect between males and females. SPSS version 10 can't do it. I checked the on-line help, and it looks like you have to use the command language. Well really, what student is going to manage that? It's out of the question. Sure, you can get a p value for the interaction, but I want confidence limits for the difference between males and females. I've got my students to convert the p value, the degrees of freedom, and the observed value of the effect into confidence limits, but I shouldn't have to resort to that. I'd also like SPSS to do an ANCOVA, but again I want to do contrasts for the interaction, and again, they ain't there. Or did I miss something? If so, please let me know. And can you let me know of any simple, and preferably CHEAP or FREE, packages that will do what I want?

I haven't used the Gini coefficient in the last 25 years, so I can't give more complete advice. However, from your description, you can can get such a sum without a macro by RANK VARIABLE= income (d) /rank into r_income. * to get the rank for each case. WEIGHT BY r_income. * to turn on weighting. DESCRIPTIVES VARIABLES= r_income /statistics=sum. Isn't the graph that the GINI coefficient summarizes something like X= proportion of people with this income or lower Y= proportion of dollars to people with this income or lower? p.s. check what you want to do with ties.

Re: How can I analyze split-design by SPSS v9.0?
Anuvat -- Here comes my "standard" comment! 1. State your research question(s) in "natural language". 2. Create a model that enables you to answer the "natural language" questions that YOU WANT. 3. Impose restrictions on YOUR MODEL that answers YOUR questions of interest. 4. Use the computer to get YOUR DESIRED RESULTS. Then AFTER YOU HAVE VERIFIED THAT THERE EXISTS A "PACKAGED" ALGORITHM THAT ANSWERS YOUR QUESTIONS OF INTEREST, THEN USE THE "PACKAGED" ALGORITHM. Since many "interesting" research questions involve creating models for unique problems, it can be more efficient to create your OWN MODELS rather than searching for "packaged" algorithms that MAY fit YOUR research questions of interest. IMHO it seems best to take time to develop "model-creation" skills so that you can have the POWER that is available.

Re: I need help!!! SPSS and Panel Data
On Sun, 2 Jul 2000 [EMAIL PROTECTED] wrote: Help! I'm a Norwegian student who can't figure out how to work SPSS 9.0 properly for running a multiple regression on panel data (longitudinal data or cross-sectional time-series data). My data set consist of financial data from about 300 Norw. municipalities. For each municipality I have observations for 7 fiscal years. My problem is that I don't know how to "tell" SPSS that the cases are grouped 7 by 7, i.e that they are panel data. Can somebody please help me! Ketil Pedersen Hi Ketil, I'm not familiar with time series terminology, but if I followed you, you have a data file that looks something like this: MUNICIP YEAR Y 1 1 1 2 1 3 etc 1 7 2 1 2 2 2 3 etc 2 7 3 1 3 1 etc 3 7 etc I think you may have one or more "between-groups" variables too, but wasn't sure about this. Anyway, if this is more or less accurate, then I think you would find it easier to use UNIANOVA rather than REGRESSION. In the pulldown menus, you find it under GLM--Univariate, I think. Here's an example of some syntax for the data shown above with SIZE included as a between-municipalities variable: UNIANOVA y BY municip year size /RANDOM = municip /METHOD = SSTYPE(3) /INTERCEPT = INCLUDE /EMMEANS = TABLES(year) /EMMEANS = TABLES(size) /EMMEANS = TABLES(year*size) /CRITERIA = ALPHA(.05) /print = etasq /plot = resid /DESIGN = size municip(size) year year*size . Note that municip is a random factor here (i.e., it is treated the same way Subjects are usually treated). And the notation "municip(size)" indicates that municip is nested in the size groups. The output from this syntax will give you an F-test for size with municip(size) as the error term; and for the year and year*size F-tests, the error term (called "residual") will be Year*municip(size), because that's all that is left over. You can get the same F-tests using REGRESSION, but not as easily. For one thing, you have to compute your own dummy variables for MUNICIP and YEAR; and if you have a mixed design (between- and within-municipalities variables), you pretty much have to do two separate analyses, as far as I can tell. Hope this helps. -- Bruce Weaver [EMAIL PROTECTED] http://www.angelfire.com/wv/bwhomedir/ === This list is open to everyone. Occasionally, less thoughtful people send inappropriate messages.

Re: SPSS GLM - between * within factor interactions
I'm not sure if this will work for your experiment but have you tried respecifying the model in terms of a nested design. Using syntax you can type A(B) in the DESIGN subcommand which means A nested within B. The code example below would fit the model Y = Constant + A+ B(A) UNIANOVA Y BY A B /METHOD = SSTYPE(3) /INTERCEPT = INCLUDE /CRITERIA = ALPHA(.05) /DESIGN = A B(A) . So you get tests for the main effect of A and the effect of B within A. "Johannes Hartig" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Help with SPSS question
Hi Julian, I have had a quick look at your data set. I decided the achievement categories were ordinal and numbered them 1 to 4. I looked at scattergraphs of grade versus frequency grouped by gender and also grouped by subject. There didn't seem to be a lot of gender difference apart from those not attempting French. There were more subject differences - a lot did not attempt French, maths did better than French in grades c and d. I did a chi^2 test for gender differences in the grades. It was significant at 0.1 but not at 0.05. The subject difference in the grades was much more significant. For these I used a 4 by 2 table adding the appropriate frequencies for each cell. Looking at your question I see you asked for gender difference in grades for the subjects separately. I combined the two. It would be easy to do them separately. I hope this helps.

Re: Bug in SPSS or SYSTAT regression ?
[EMAIL PROTECTED] wrote: I have found a difference between the results produced by SPSS and SYSTAT in linear regression with no constant term. Below are the results from the programs. As you can see the adjusted R2 given by the 2 programs is different. Which one is correct? Quoting from the SysStat FAQ, (1) In the presence of a constant, R^2 measures variation around the mean of the dependent variable which is explained by the variation around the mean of the independent variables. (2) Without a constant, R^2 measures variation around zero of the dependent variable which is explained by the variation around zero of the independent variables. I found the following in "Applied Linear Statistical Models" 4th ed by Neter, Kutner, Nachtscheim, and Wasserman (Irwin publishing, 1996) p. 163: " 3. Some statistical packages calculate r^2 for regression through the origin to (2.72) and hence will sometimes show a negative value for r^2. Other statistical packages calculate r^2 using the total uncorrected sum of squares SSTOU in (2.54). This procedure avoids obtaining a negative coefficient but lacks any meaningful interpretation." So in essense, calculating R^2 and the F-statistic for model not containing a y-intercept is dangerous. For the un-experienced user, the meaning is easily misinterpreted. It appears as if the statisticians are telling us that there is no proper way or best way to calculate these values. Hope that helps. -Tony === This list is open to everyone.

Okay, that is the *abnormal* way to do regression, which sacrifices (for one thing) the ease of referring to R-squared. Are you talking about accounting for the SS around the MEAN, or around ZERO? c) I prefer to continue talking about SS around the MEAN, and if you did that, then you *might* continue ( - but, no assurances) to use the ordinary 'shrinkage' formula to get an "adj R2". d) When you have those values of .999+, as above, the easy way to get them (with all-positive numbers) is to have the SS around ZERO.I *assume* that the usual shrinkage formula has to be modified, if anyone has come up with a formula at all. Thus, I conclude that SYSTAT decided not to provide an adjusted R2, possibly because there is nothing reliable or conventional in the literature. SPSS probably provided one, if their distinction is not round-off error. I would want to check their references before I trusted in reporting it; but I am concerned, that almost no one uses that computation (through the origin/ SS around zero), and that was not emphasized in the question. If using that if it is not a convention, already, in your area of specialty, then you have enough troubles explaining why you used that regression ... without getting into the details of *that* adjusted R-squared. -- Rich Ulrich, [EMAIL PROTECTED] http://www.pitt.edu/~wpilib/index.html === This list is open to everyone.

Re: Bug in SPSS or SYSTAT regression ?
The multiple correlation between X and Y does not depend on if there is a constant term in the regression or not. The residual sum of squares does. R2 is simply 1.0. Basically, the answer is: both are quite incorrect, or: only two decimals are correct. Although I hate to pretend to correct Jan in anyway, I will: YEP both are incorrect but the correlation squared between X and Y is not necessarily the answer one wants for R2, is it? There are two interpretations for R2 - 1. The correlation squared between the predicted and actual; 2. The percentage explained variance. With a constant term in least squares the two are identical. Without a constant term the two can and in this case do differ. The correlation between the actual and fitted values of regressing Y on X is 1.0, so an answer to 1. produces the same answer as the correlation between Y and X. But the residuals are not identically 0 so one might not like to argue that R2 should be 1. since one would expect (at least I would) that the residuals should be 0 for R2 = 1.000 (up to numerical accuracy anyway). The residuals are: 5.537190 4.462810 3.388430 2.314050 1.239669 0.165289 -0.909091 -1.983471 -3.057851 -4.132231 -5.206612 with a mean of .165289. The problem, without the constant term, is that the decomposition of sums of squares is not the usual ssqc(Y) = ssqc(X) + ssq(res) (ssqc = sum of corrected squares) from which most programmers make their calculation of R2 (many packages will report R2 = -0.157025 in this particular case). We are left with a lot of different answers R2 = ssqc(X)/ssqc(Y) = 1.0 (because this is the correlation between Y and X) = ssq (X)/ssq (Y) = .232246 = 1 - (ssqc(res)/ssqc(Y)) = -.154293 = 1 - (ssq (res)/ssq (Y)) = .999365 which is what SYSTAT and SPSS report (assuming that I did my calculations correctly) Maybe some others on the list can point to theoretical pieces on R2 of which I am unaware to single out one of these. I tend to like the second one. In the end, IMHO, NEVER do regression without a constant term.

Re: SPSS lab guide for mulitvariate stats.
As a lab guide, SPSS for Windows Step by step is very good (authors: George and Mallery, publisher : Allyn and Bacon). There is also a very good book for psychologists: Tabachnick and Fidell, Using multivariate statistics. The only problem is that it does not have cluster analysis. At 14:29 2000-02-11 -0500, Paul W.

help junior spss user
Dear all, I would like to know which statistical method should I use for my research with SPSS. My research aims at examining the causal relationship of sport training program to academic results. Thus, I collected the academic results before and after the training program from sport participants and also the non-sport participants as the control group. Besides, as I want to know how the training program affects the academics, I also collected the pretest and posttest data of self-esteem and motivation from both experimental and control groups. Thus, I can examine the relationship between self-esteem, motivation and sports. Can anyone help me to solve this big problem for a junior SPSS user? Thanks. Alice === This list is open to everyone.

Re: repeated measures ANOVA + SPSS
Hi, aber ich glaub ich antworte mal auf deutsch.
Mein Vorschlag zur Lösung deines Problems, so ich es richtig verstanden habe
würde so aussehen:
20 Patienten
1 Variable (Herzfrequenz, hf)
10 Meßzeitpunkte (m1-m10)
unter GLM mit Meßwiederholung als Innersubjektfaktor (is doch echt ein
klasse Name:) ) einen Namen
wie zB hf und als Anzahl der Stufen 10 angeben und "Hinzufügen".
In der folgenden Dialogbox als Innersubjektvariablen die m1 bis m10 für die
hf hinzufügen.
So könnte man einen weiteren Wert (RR sys ) und dessen Meßwiederholung auch
noch definieren.
Zwischensubjektfaktoren wären z.B. Alter oder Geschlecht, sofern für die
Fragestellung relevant.
Kovariaten wären bei Ausgangslagenunterschieden anzugeben.
soweit also alles wie Du vorgesehen hast, nun aber die schlechte Nachricht,
post-hoc Tests sind in SPSS nur für
Designs ohne Meßwiederholung implementiert. Bei Signifikanzen in dieser
Analyse bleibt nur der paired t-test.
Ich hoffe für die schnelle ist Dir geholfen.
Viele Grüße aus Lübeck

Hi to all the experts,
I measured a few Variable in let´s say 20 Patients under 10 different
conditions, f.e.heart rate at 10 different exercise levels.
1.) To compare the results I understood that I have to use a repeated
measures ANOVA, am I correct?
2.) If I want to use SPSS, where do I find that test? If I understood
the Online-Help correctly then I should use "GLM-Messwiederholungen"
(sorry for the German version, in English that would probably be
something like "GLM-repeated Measures"??)
3.) Great! ? Here I have to define several things, that I do not really
understand - o.k. let´s try: I give the "Innersubjectfactor" (that´s how
it sounds in German") a name and tell SPSS how many repeated measures I
performed.is that correct ??
4.) If I go on, on the next screen I have to define the different
measurment/variables - however if I leave the two boxes below ("between
subject factors" and "covariates") open, then SPSS won´t let me define
any post-hoc-test , why not??? I understood that "between subject
factors" has something to do with f.e. male and female ?? So, do I
really have to define that or can I leave it open??
Any comments or help is very appreciated!!!
Thank you for your patience
