%goflogit Errors

[altijani]

I am running the %goflogit Macro for the goodness-of-fit of the Logit model I am running. Right off the bat, I have these errors, and I don't really know what they mean or what I should do to remedy the issue. These errors keep repeating 61 times. I found this post, which again can not pin to the problem I am facing: http://blogs.sas.com/content/iml/2010/11/29/how-to-interpret-sasiml-error-messages.html

Any help is highly appreciated.

Here is the output:

308 %goflogit (data=b, y=Y, xlist=X1 X2 X3 X4 X5 X1*X1, trials=num)

You need to specify valid variable names that exist in the data set. The macro does not interpret interaction terms like X1*X1.

Instead, you need to generate the interaction yourself and create a new variable that contains the interaction term.

For information about how to create a design matrix, see 

"Four ways to create a design matrix in SAS"

or use the DATA step to create the interaction.
