PPT-Does your logistic regression model suck?

PERFECTION This is bad Model Convergence Status Quasicomplete 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.
