$$Excel-Macros$$ Probability (Gaussian) Distributions with known means and standard deviations using existing excel functions

2011-08-01 Thread Michael Hayes
Okay, I have a series of numbers like the table below:



Value 1 Value 2  Value 3Value 4 Value 5 Value 6 
MeanSt
Dev ~% Prob
Series A67.09   64.31   70.47   64.43   54.73   64.21   5.86
  4.66%
Series B68.60   59.70   62.27   74.55   70.14   67.05   6.02
  6.17%
Series C66.28   68.31   62.86   72.61   66.58   67.33   3.56
  9.60%
Series D61.16   67.95   71.56   68.33   75.88   68.98   5.41
  7.36%
Series E62.02   68.27   68.97   68.25   68.81   67.27   2.95
 10.63%
Series F66.44   71.39   67.27   69.69   63.56   67.67   3.02
 11.40%
Series G65.52   66.27   68.29   70.05   65.72   67.17   1.95
 11.19%
Series H65.99   67.85   66.98   70.59   69.76   68.24   1.91

 10.20%


69.31296719 1.0


What I want to determine is the probability (based on the mean and
standard deviation) for each series that the next value will be the
highest value in the empty column. For example what is the probability
that the next value in Series 1 will be the highest value in column
"Value 6". I think the answer is roughly 4.66%

I can do a rough approximation using normdist on some dummy variable
and the using solver have the sum of the normdist probabilities sum to
1. Thats how I generated the numbers in the last column. Alternatively
I can do Monte Carlo simulations, but thats time consuming. So I'm
looking for a more elegant and precise solution using the existing
functions in Excel!

I believe the general equation has the form below:

Prob{t(min\A) < x} = Prob{min{t(B), ..., t(J)} < x} = Prob{not all
{t(B), ..., t(J)} > x} = 1 - Prob{all {t(B), ..., t(J)} > x} =
1−∏k∈(S∖A)[1−Φk(x)]
where Φk is the Gaussian CDF for t(k).

Although the above equation is for the probabilities for the lowest
value, I'm guessing substituting "max" for "min" and "<" for ">" will
get the right equation. The question then is, can you solve the
equation in excel? And how difficult is it?

Thank you in advance for any assistance you can provide.

$$Excel-Macros$$ Auto Formatting

2011-06-30 Thread Michael Hayes


When I do web queries and create pivot tables in Excel 2007, I really
dislike the automatic column width formattingthe columns are often
so narrow that my data is unreadable...is there a way to turn off the
auto column format function?

$$Excel-Macros$$ Web Data Queries

2011-05-02 Thread Michael Hayes
I just downloaded the Excel 2007 Web Data Add-in...I have two general
questions:

1. I cant seem to get a web page from a secure server (https) to
load...are there any issues here?
2. I have gotten data from a page like Yahoo finance, but once the
data is imported it is static...how do you keep the data dynamic. For
example how do you have the DJIA (Dow Jones Industrial Average) change
in the spreadsheet as soon as it changes in Yahoo?

I"m guessing these questions may be addressed in the tutorial, but the
link to the tutorial is broken...so I would appreciate any insights.

Steve,

Lets assume that your columns are labeled A, B & C. meaning that cell
A2=2, B2=3, C2=5

put this formula in cell C2, =IF(B2="",A2+C1-A1,B2+A2)

Copy that formula down.

Re: $$Excel-Macros$$ Need help with a formula

2010-08-19 Thread Michael Hayes
Beckie or is it Becky?

Im hoping someone has a more elegant solution than I do...the only way
I know how to do it is to create three additional columns.

In cell AZ3 I put this formula

=IF(R3="NA",IF(T3="NA",IF(V3="NA",IF(X3="NA",IF(Z3="NA",IF(AB3="NA",IF(AD3="NA","NOT
CLOSED",AC$1),AA$1),Y$1),W$1),U$1),S$1),Q$1)

In cell BA3 I put this formula

=IF(AF3="NA",IF(AH3="NA",IF(AJ3="NA",IF(AL3="NA",IF(AN3="NA",IF(AP3="NA",IF(AR3="NA","NOT
CLOSED",AQ$1),AO$1),AM$1),AK$1),AI$1),AG$1),AE$1)

and in cell BB3 I put this formula

=IF(AT3="NA",IF(AV3="NA",IF(AX3="NA","NOT CLOSED",AW$1),AU$1),AS$1)

Copy those formulas down your sheet

Then in Cell P3 I put this formula

=IF(MIN(AZ3:BB3)=0,"NOT CLOSED",MIN(AZ3:BB3))

Copy that down.

This will solve your problem until someone provides a more concise &
elegant solution.

Alex,

This a "Text to Columns" function. Select the column, use the Text to
Columns/ delimited function with "space" as an indicator.

In Excel 2007 "Text to Columns" can be found on the Data tab.

$$Excel-Macros$$ Re: find a value of intersection of two graph in excel

2010-08-06 Thread Michael Hayes
Cell B4 isnt blank...I suggested that he put his X Axis coordinates
beginning in cell B4. In cell B4, I said enter the number 1. In cell
C4 enter the number 2 etc. Part of the difficulty in solving the math
behind this problem is that there were missing variables. The X axis
coordinates were missing. I suppose you could impute the X axis
coordinates (using a count function), but I choose not to do that.

Cell C5 may or not be blank depending on the series of numbers in row
2 and row 3. If there is no intersection between those series values
(C2 & C3) and the prior series values ( B2 & B3) the formula in cell
C5 will return "N/A". If there is an intersection, then cell C5 will
not be blank.

$$Excel-Macros$$ Re: find a value of intersection of two graph in excel

2010-08-05 Thread Michael Hayes
Sudhir,

I am assuming by the subject matter of your posting you need to find
the X and Y coordinates of any place on the graph where series 1 and
series 2 intersect. So if I understand your request correctly, this
should help

Lets put your X axis coordinates in cells B4 through E4. So in cell B4
enter 1, in cell C4 enter 2 etc.

Then starting in cell C5 put this formula to determine if there is an
intersection =IF((B2-B3)*(C2-C3)>0,"N/A",B4+(B2-B3)/((B2-C2)-(B3-C3)))
Copy that formula to cells D5 and E5

That formula will tell your X axis coordinate of intersection (if
applicable)

Then in cell C6 enter this formula =IF(C5="N/A","N/A",+B2-((B2-C2)*(C5-
B4))) copy that formula over to cells  D6 and E6

That formula will tell you your Y axis coordinate where the graphs
intersect (if applicable)

Email directly if you need a copy of the edited spreadsheet.

Re: $$Excel-Macros$$ IN THE SENTENCE REQUIRE ONE CELL VALUE

2010-06-16 Thread Michael Hayes
Hameet,

Try the concatenate function

=CONCATENATE("I have "&B1&" hands and "&C1&" Eyes")

Notice the spaces for the text inside the quotation marks...you need
those spaces to format your sentence properly.

Re: $$Excel-Macros$$ Legal Notice/Splash Screen

2010-06-14 Thread Michael Hayes
Dave

In general I agree with you. The algorithms can be copied. The catch
here is that only parties that would be interested in my algorithms
are large insurance carriers with deep pockets. Concurrent with
writing this program, I'm also serving as an expert witness for a very
large insurance company who is alleging intellectual property theft by
a competitor. Millions of dollars are at stake. And a large portion of
the intellectual property at issue are a series of spreadsheets I
developed in the 90's. I didnt think the stuff I did in the 90's was
all that clever or unique, so I didnt do anything to protect what I
was doing. Now 15 years later, there is this big lawsuit and I can see
now what I could have done to make my clients case stronger. So, this
legal case has made me more cautious...I know I cant prevent copying,
I just want anyone who does copy or steal the program to do so with
clear knowledge of the potential liability associated with such acts.
And hey if they do steal my work again, I'll be flattered and then let
the attorneys handle everything.

Thanks for your input.

Michael Hayes

Kavita,

Thank you. I have been using this book as a coaster: "Excel 2007 VBA
for Dummies"...looks like I'm going to have to read it now. I think
I'm going to need more coffee.

$$Excel-Macros$$ Legal Notice/Splash Screen

2010-06-13 Thread Michael Hayes
Good Afternoon to all,

I'm developing a spreadsheet to calculate insurance rates for a large
client. Within the spreadsheet are some highly proprietary algorithms
that I developed that describe the relationships between costs and
"richness" of benefits.My client believes this spreadsheet/program
will have some definite commercial value upon completion. So basically
I need to think about intellectual property protection. Therefore I
have two questions:

Any advice on the simplest way to provide some degree of intellectual
property protection on a spreadsheet or the algorithms within the
spreadsheet?
Any way to create a "splash screen" or some legal notice that pops up
whenever the program is opened? And the user cant continue without
acknowledging the notice?

Thanks

Michael Hayes
