statsmodels.regression.linear_model.OLS.loglike¶ 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:¶ The likelihood function evaluated at params. Return type:¶ float
