statsmodels.genmod.families.family.Binomial.initialize

Binomial.initialize(endog, freq_weights)

Initialize the response variable.

Parameters:

• endog (ndarray) – Endogenous response variable

• freq_weights (ndarray) – 1d array of frequency weights

Returns:

• If endog is binary, returns endog

• If endog is a 2d array, then the input is assumed to be in the format

• (successes, failures) and

• successes/(success + failures) is returned. And n is set to

• successes + failures.
