Excel Graphics
Not sure if this is the best place to ask, but can anyone point me towards any web sites that provide advice on using Excel for technical/scientific graphing. I am not sure why exactly, but I find the graphs produced by Excel, compared to S-Plus or Statistica, to look out of place in a technical report. As I know others feel the same way, I was hoping that there might be some advice out there on how to improve their appearance.

Re: article on Excel errors
i don't think so ... you need acrobat reader though http://www.elsevier.nl/gej-ng/10/15/38/37/25/27/article.pdf At 02:26 PM 1/27/01 +, [EMAIL PROTECTED] wrote: >Except it seems to be restricted to people who have a subscription to >the journal.

Re: Excel Graphics
One piece of advice I received on this topic was: Use DeltaGraph. Even 4.0 (ca 1997) offers more options, and display control.

A-D in matlab
Hi
Out of curiousty i decided to write a small prog to perform the A-D test in
matlab for the gumbel distribution. Obtaining the gumbel parameters is easy.
however the difficulty is in the actual A-D computation formula as stated by
Stephens(1977).
A2=-[Sum(i=1,n)(2i-1){logzi+log(1-zn+1-i)}]/n-n
whats the point of /n and -n since they both cancel out anyway. regardless
of this, i still get extremely large values of A2. I checked my file using a
different distribution and compared that value with SAS and it was totally
wrong.
can anyone point out whats wrong in the m file below
function adtest;
cd c:\
cd data
cd 1k
An=[ ];
x=load('ratio_error_1');
[phat,cov]=wgamfit(x,0); %estimating gumbel parameters
f=wgampdf(x,phat(1,1),phat(1,2)); %creating the gumbel equivalent data based
%upon the above parameters
f=f';
b=1000:-1:1;
minus_f=f(b);
%computing the A-D statistic
A=-1000-(1/1000)*sum((2.*(1:1:1000)-1).*(log(f(1,1:1:1000))+log(1-minus_f(1,
1:1000
thanks

Uh-huh. Perhaps you need to consider the difference between
A2 = - [long expression]/n - n
and
A2 = - [long expression]/(n - n).
The latter of course is infinitely large.
In your program, you appear not to have divided by n, which surely
means that your value of A2 will be n times too large, even if you
have correctly computed [long expression].
