Quasi-complete separation in Multinomial Logistic Regression

Troubleshooting


Problem

I have performed a Multinomial Logistic Regression, but received these warnings: There is possibly a quasi-complete separation in the data. Either the maximum likelihood estimates do not exist or some parameter estimates are infinite. The NOMREG procedure continues despite the above warning(s). Subsequent results shown are based on the last iteration. Validity of the model fit is uncertain. What does this mean? Can my results be trusted?
