statsmodels.regression.linear_model.OLS.loglike

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:

Return type:

The likelihood function evaluated at params.
