ERROR: Computations are terminated because the number of response levels, 264, exceeds MAXRESPONSELEVELS=100.

this is the error I am getting after running this code. I don't know what to do. Please help

The most common use of logistic regression is to predict a binary variable. Thus (often) your Y variable would have only two values 0 and 1.

The error is saying that your Y variable has more than 100 levels. Probably you are either 

1. Using the wrong variable as the response. Is there a different variable that is binary?

2/ Using the wrong procedure. If Y is a continuous variable (rather than binary), then you should use PROC GLM or some other variable that models continuous responses.
