loglike(endog, mu, freq_weights=1.0, scale=1.0)¶
The log-likelihood in terms of the fitted mean response.
endog : array-like
Endogenous response variable
mu : array-like
Fitted mean response variable
freq_weights : array-like
1d array of frequency weights. The default is 1.
scale : float, optional
Scales the loglikelihood function. The default is 1.
llf : float
The value of the loglikelihood function evaluated at (endog,mu,freq_weights,scale) as defined below.
If the link is the identity link function then the loglikelihood function is the same as the classical OLS model.
If the links is not the identity link then the loglikelihood function is defined as
