statsmodels.regression.mixed_linear_model.MixedLM.get_scale

MixedLM.get_scale(fe_params, cov_re, vcomp) [source]

Returns the estimated error variance based on given estimates of the slopes and random effects covariance matrix.

Parameters:	fe_params (array-like) – The regression slope estimates cov_re (2d array-like) – Estimate of the random effects covariance matrix vcomp (array-like) – Estimate of the variance components
Returns:	scale – The estimated error variance.
Return type:	float
