I used the expression below as suggested by Donald:
A2 =( - [long expression]/n) - n
but still getting some fairly large values.
thanks

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
