Methods
deviance(endog, mu[, var_weights, …])The deviance function evaluated at (endog, mu, var_weights, freq_weights, scale) for the distribution.
fitted(lin_pred)Fitted values based on linear predictors lin_pred.
loglike(endog, mu[, var_weights, …])The log-likelihood function in terms of the fitted mean response.
loglike_obs(endog, mu[, var_weights, scale])The log-likelihood function for each observation in terms of the fitted mean response for the distribution.
predict(mu)Linear predictors based on given mu values.
resid_anscombe(endog, mu[, var_weights, scale])The Anscombe residuals
resid_dev(endog, mu[, var_weights, scale])The deviance residuals
starting_mu(y)Starting value for mu in the IRLS algorithm.
weights(mu)Weights for IRLS steps
