statsmodels.genmod.families.family.Gaussian¶

class statsmodels.genmod.families.family.Gaussian(link=None, check_link=True)[source]¶

Gaussian exponential family distribution.

Parameters:¶

linka link instance, optional

The default link for the Gaussian family is the identity link. Available links are log, identity, and inverse. See statsmodels.genmod.families.links for more information.

check_linkbool

If True (default), then and exception is raised if the link is invalid for the family. If False, then the link is not checked.

Attributes:¶

Gaussian.linka link instance

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.
get_distribution(mu, scale[, var_weights])	Frozen Gaussian distribution instance for given parameters
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 Gaussian 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
