OLS.loglike(params, scale=None)

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:

The likelihood function evaluated at params.
