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
