statsmodels.regression.mixed_linear_model.MixedLM.get_fe_params¶ MixedLM.get_fe_params(cov_re, vcomp, tol=1e-10)[source]¶ Use GLS to update the fixed effects parameter estimates. Parameters:¶ cov_re : array_like (2d)¶The covariance matrix of the random effects. vcomp : array_like (1d)¶The variance components. tol : float¶A tolerance parameter to determine when covariances are singular. Returns:¶ params (ndarray) – The GLS estimates of the fixed effects parameters. singular (bool) – True if the covariance is singular
