Likelihood

Likelihood(name, params=None, parent=None, dist=None)

Representation of a Likelihood function for a Bambi model

Parameters

name : str

Name of the likelihood function. Must be a valid PyMC distribution name.

params : sequence of str or None = None

The name of the parameters the likelihood function accepts.

parent : str or None = None

Optional specification of the name of the mean parameter in the likelihood. This is the parameter whose transformation is modeled by the linear predictor.

dist : pymc.Distribution or callable or None = None

Optional custom PyMC distribution that will be used to compute the likelihood.

Notes

• parent must be in params
• parent is inferred from the name if it is a known name
