statsmodels.discrete.count_model.ZeroInflatedNegativeBinomialP.loglikeobs

ZeroInflatedNegativeBinomialP.loglikeobs(params)

Loglikelihood for observations of Generic Zero Inflated model.

Parameters:
paramsarray_like

The parameters of the model.

Returns:
loglikendarray

The log likelihood for each observation of the model evaluated at params. See Notes for definition.

Notes

\[\ln L=\ln(w_{i}+(1-w_{i})*P_{main\_model})+ \ln(1-w_{i})+L_{main\_model} where P - pdf of main model, L - loglike function of main model.\]

for observations \(i=1,...,n\)
