residual plots logistic regression

Hi,

How to I make a residuals plot for a logit model? I only found this link. But I would like to plot the residuals against one of the independent variables, not just "by case number". What options do I use?

Thanks in advance.

You can use the options in the OUTPUT statement to save any residuals that you like. Then, with the resulting data set, you can construct the plot you want using PROC SGPLOT.

Thanks, sounds good. Can you provide some details on how to output residuals?

It's always necessary to see the syntax information in the procedure documentation. There are several types of residuals. Adding this would save the Pearson and deviance residuals in a data set called MyRes.

output out=myres reschi=rc resdev=rd;
