Binomial.initialize(endog, freq_weights)[source]

Initialize the response variable.

Parameters: endog (array) – Endogenous response variable freq_weights (array) – 1d array of frequency weights 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.
