[Statistica] logistic regression


I have been getting a bunch of errors with Statistica when trying to created a logistic regression model.

I use the Generalized Linear/Non-linear tab then go to logit model.

The problem I have is that after I load up my variables and try to make a forward stepwise model I get an error that says Mathematical error occurred in the estimation procedure. This error implies wrong specification of the model. Please check for appropriate distribution and link function. I'm not sure what this means, and it only seems to be an issue with certain groups of continuous predictors, ie variables 1-18 will work but 1-19 wont and 16-26 will also work, so I'm not sure what the issue is.

Thanks to anyone who can help.
in order to help you, I need to know the number of participants, the number of variables, the nature (categories, nominal).
Maybe you should present the model you would like to test.
