class statsmodels.base.model.GenericLikelihoodModelResults(model, mlefit)[source]

A results class for the discrete dependent variable models.

..Warning :

The following description has not been updated to this version/class. Where are AIC, BIC, ….? docstring looks like copy from discretemod

Parameters
modelA DiscreteModel instance
mlefitinstance of LikelihoodResults

This contains the numerical optimization results as returned by LikelihoodModel.fit(), in a superclass of GnericLikelihoodModels

Attributes
aicfloat

Akaike information criterion

bicfloat

Bayesian information criterion

bsearray

The standard errors of the parameter estimates.

df_residfloat

See model definition.

df_modelfloat

See model definition.

fitted_valuesarray

Linear predictor XB.

llffloat

Log-likelihood of model

llnullfloat

Value of the constant-only loglikelihood

llrfloat

Likelihood ratio chi-squared statistic; -2*(llnull - llf)

llr_pvaluefloat

The chi-squared probability of getting a log-likelihood ratio statistic greater than llr. llr has a chi-squared distribution with degrees of freedom df_model.

prsquaredfloat
