I have a question, why should I subtract the mean value in the Cox time varying formula?  For example, in this example, the actual mean value of var1 should...

Thank you for your answer, but in results containing interaction items, this can cause interpretation headaches.For example，  β3 means the coefficient when prio takes 0, but after subtracting the...

Sorry, I don't quite understand what is meant by subtracting the mean after the interaction term occurs, I used the equation below for the fit and when the results are...

Am I to understand that subtracting the mean is doing the centering? If I have centered the matrix (subtracted the mean) before fitting, is subtracting the mean invalid?

Thank you so much！I'm much clearer！By the way， > there should not be a subscript i in the Xbar i on for Cox time varying formula. subscript i is still...

> You'll have to use pandas to manipulate the dataframe prior to providing it to .fit then. Ex: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.get_dummies.html Could you tell me if I am using a formula, do...
