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 : float
The estimated error variance.
