statsmodels.regression.linear_model.OLS.score

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

Evaluate the score function at a given point.

The score corresponds to the profile (concentrated) log-likelihood in which the scale parameter has been profiled out.

Parameters:	params (array-like) – The parameter vector at which the score function is computed. 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 score vector.
