Hi there and good mrning from the Netherlands, I am a novice user of the SAS University Edition and I have performed a logistic regression analysis with 176 cases, 1 dichotome dependent variable, of course, 5 categorical independent variables and 10 continuous independent variables. The results were, as expected, unreliable because of unusual high standard errors. So I decided to do a exact logistic procedure with the following code. However, after 2 1/2 hrs ths system had not yet replied with results. I could have waited for the default seven days but that would not be very practical. My question is: which inefficiencies can be discovered in the code ? Thank you very much for your suggestions. regards, Nico Verhoef, student Open University. ods noproctitle; ods graphics / imagemap=on; proc logistic data=WORK.IMPORT; class GENDER AGE PRACTYPE WORKHRS PRACYRS / param=glm; model EXC_PRES(event='1')=GENDER AGE PRACTYPE WORKHRS PRACYRS WAItot WAI1 WAI2 WAI3 WAI4 WAI5 WAI6 WAI7 EE DP / link=logit technique=fisher; exact GENDER AGE PRACTYPE WORKHRS PRACYRS WAItot WAI1 WAI2 WAI3 WAI4 WAI5 WAI6 WAI7 EE DP; exactoptions method=networkmc; run;
