OLS.loglike(params, scale=None) [source]

The likelihood function for the OLS model.

Parameters:	params (array-like) – The coefficients with which to estimate the log-likelihood. scale (float or None) – If None, return the profile (concentrated) log likelihood (profiled over the scale parameter), else return the log-likelihood using the given scale value.
Returns:
Return type:	The likelihood function evaluated at params.
