Content-Type: text/plain; charset=iso-8859-1

Hi all?

suposse this data (i finally got and exported after many calculations):

Obs diff COUNT PERCENT

1       0      6      27.2727

2       1     11     50.0000

3       2      3      13.6364

4       3      2        9.0909



Now i need make varoius formulas for X, like:



1) X1=a/b +c*d

2) X2=(a+b) / (c-d)

3) X3=(a-b) / (a+b+c+d/2)



etc...



where:

a= percent of record where diff=0

b= percent of record where diff=1

c= percent of record where diff=2

d= percent of record where diff=3



my variable diff is always ordened



its possible?



thx in advance,

Adriano
