proc logistic score

hello, people,

I have met this problem that when I run the score statement, the oversampling part is wrong, can anyone help me figure it out? (here is the screen shot of the problem).

thanks.

Your issue is a macro variable reference that doesn't resolve, resulting in invalid syntax.

Where are you setting the value of &pi1?

Your code makes reference to a macro variable called "p1." Where you use it in the code, it should resolve the name of a variable in your score data that has the prior probability of an event. I have absolutely no way to know what the name of that variable is, but I think you have a few options.

If you know what the variable is supposed to be, you can 1) hard code it so that "priorevent = your_variable" or 2) set p1 to the variable value with "%let p1 = your_variable" above your proc logistic. Alternately you can try just removing the "priorevent=&p1" from your code, but if it was there before, it's likely there for a reason.

thank you, it is solved by correcting the data path, and the priorevent = &pi doesn't change.
