Poisson.loglike()

statsmodels.genmod.families.family.Poisson.loglike

Poisson.loglike(endog, mu, freq_weights=1.0, scale=1.0) [source]

The log-likelihood function in terms of the fitted mean response.

Parameters:	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 The scale parameter, defaults to 1.
Returns:	llf : float The value of the loglikelihood function evaluated at (endog,mu,freq_weights,scale) as defined below.
