Hi, what is the ideal Pvalue which tells the model is in good fit in H-L Goodness fit test. My understanding is lower the pr>chi sq, better the model. How low it should be. ... View more

HI, How do I check built Logistic regression model is suffering with BIAS or Variance. I learnt about c-statistics, H-L Goodness -of-Fit Statistics, they all say how well the model is fit. But how can I interpret that the built model will perform better in unseen data. Please help to understand. Really struggling to get answer to this.     ... View more

Hi, I am very new to SAS Stats and running Logistic regression.   I am looking to get answer for two questions 1. I am getting "Model Convergence status is Quasi complete Separation of data Point detected". what would be the implication of this warning and how to solve this. 2. C-statistics of validation data set is larger than C-statistics of Training set. Is this possible?  My expectation is Training set should perform better than validation data set.     Attached the report for your reference.   Could you please help to get answer for the 2 questions. ...

HI, I am new to SAS Logistic Regression.

Can you help to get similar graph in SAS. I am not sure whether it is referred by different name.  ... View more
