statistics - How to compute Studentized Residuals in Python?

Question

I've tried searching for an answer to this problem but so far I haven't found any. I used statsmodel to implement an Ordinary Least Squares regression model on a mean-imputed dataset. I can access the list of residuals in the OLS results, but not studentized residuals. How can I calculate/get studentized residuals? I know the formula for calculating studentized residuals but I'm not exactly sure how to code this formula in Python.

Thanks in advance.

UPDATE: I've found the answer. I can get a dataframe containing the studentized residuals from the outlier_test() function from OLS reults.

Answer 1

I was dealing with the same issue. The solution is to use the statsmodels library:

from statsmodels.stats.outliers_influence import OLSInfluence

It has a resid_studentized_internal method included.
