Hi Mike, why don't you separate the sample to train and test the model? Does it only apply to ML algorithms? Thank you.
Best regards from Colombia.

Hello,
I have noticed that your log likelihood is negative. Shouldn't the log likelihood be a positive number to establish that the model is a good fit? From what I know, the log likelihood should be a positive number. Is this true?
I'm dealing with a similar issue, such that I have over 300k observations. Although my variables are significant and prob>chi2 = 0.000, my log likelihood is - 207079 . Why is the log likelihood so large and negative? Is the log likelihood interpreted in absolute value? I would appreciate your assistance.
