Subject: Manual Classification Table
Content-Type: text/plain; format=flowed
hi,
I'm using Proc Logistic and am trying to compare the classification done by
SAS (using the ctable option) versus that done manually. Of course, given
that SAS uses a jackknife approach when doing it's classification table, I
don't expect to see exact results (or should I?). However, my problem at
this time is the classification results that I'm getting using the code
below -- it does not look right. Is there a way to mimic the SAS format for
producing classification tables?
thanks in advance.

*** SAS CODE ***
proc logistic data=mydata;
model y = x1 x2 / ctable pProb=(0 to 1 by 0.1);
output out=pred p=p;
data b;
set pred;
do cut=0 to 1 by .1;
class=p>cut;
output;
end;
run;
proc sort data=b;
by cut;
proc freq;
by cut;
tables class*y;
run;
