Binomial.initialize(endog, freq_weights)[source]¶

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
