statsmodels.regression.mixed_linear_model.MixedLM.get_scale

MixedLM.get_scale(fe_params, cov_re, vcomp)

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
