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.


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.


The score vector.
