Probit.loglike()

statsmodels.discrete.discrete_model.Probit.loglike

Probit.loglike(params) [source]

Log-likelihood of probit model (i.e., the normal distribution).

Parameters:	params : array-like The parameters of the model.
Returns:	loglike : float The log-likelihood function of the model evaluated at params. See notes.

Notes

Where . This simplification comes from the fact that the normal distribution is symmetric.
