What's the difference between resid_working, resid_anscombe, and resid_deviance in statsmodel.GLMResults?
Here are some explanation from the source code:
Working residuals; the working residuals are defined as resid_response/link'(mu); see links.py for the derivatives of the link functions.
Anscombe residuals; see family.py for distribution-specific Anscombe residuals.
deviance residuals; see family.py for distribution-specific deviance residuals.
