Iterative Proportional Fitting other than PROC IML

Instead of using the PROC IML to conduct the Iterative Proportional Fitting, any other methods / procedures that can be dealt with.

Wouldn't Fisher's Exact Test do what you need in PROC FREQ? At least as far as generating a probability statement about the "extremeness" of the observed proportions?  Calculating the expected proportions would be more difficult, and if that is what you need, then you will probably need to explore PROC CATMOD.

My situation is that the value in each cell is known, for instance, at the very beginning I got the following table:

var1var2
A1B2G5Total
T11030747
S225-7
S4-72981
U88-1725
Total2010733160

and suppose the control total of var1 and var2 are:

var1
T153
S219
S4102
U850
Total224

var2
A1B2G5Total
705797224

The target is to adjust the value of each cell of the var1 x var2 with the control total.
