PERFECTION!. This is bad. Model Convergence Status. Quasi-complete separation of data points detected.. Warning:. The maximum likelihood estimate may not exist..  . Warning:. The LOGISTIC procedure continues in spite of the above warning. Results shown are based on the last maximum likelihood iteration. Validity of the model fit is questionable..
