Tweedie.
loglike_obs
(endog, mu, var_weights=1.0, scale=1.0)[source]¶ The log-likelihood function for each observation in terms of the fitted mean response for the Tweedie distribution.
Parameters: Returns: ll_i – The value of the loglikelihood evaluated at (endog, mu, var_weights, scale) as defined below.
Return type: Notes
This is not implemented because of the complexity of calculating an infinite series of sums.
