resid_anscombe
(endog, mu)[source]¶ Anscombe residuals for the Poisson exponential family distribution
Parameters: endog : array-like
Endogenous response variable
mu : array-like
Fitted mean response variable
Returns: resid_anscombe : array
The Anscome residuals for the Poisson family defined below
Notes
resid\_anscombe_i = (3/2) * (Y_i^{2/3} - \mu_i^{2/3}) / \mu_i^{1/6}
