Tweedie.loglike()
statsmodels.genmod.families.family.Tweedie.loglike
-
Tweedie.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
The fitted mean response values
freq_weights : array-like
1d array of frequency weights. The default is 1.
scale : float
The scale parameter. The default is 1.
Returns: llf : float
The value of the loglikelihood function evaluated at (endog,mu,freq_weights,scale) as defined below.
Notes
This is not implemented because of the complexity of calculating an infinite series of sums.
