statsmodels.regression.mixed_linear_model.MixedLM.loglike¶
method
-
MixedLM.
loglike
(params, profile_fe=True)[source]¶ Evaluate the (profile) log-likelihood of the linear mixed effects model.
- Parameters
- paramsMixedLMParams, or array-like.
The parameter value. If array-like, must be a packed parameter vector containing only the covariance parameters.
- profile_feboolean
If True, replace the provided value of fe_params with the GLS estimates.
- Returns
- The log-likelihood value at `params`.
Notes
The scale parameter scale is always profiled out of the log-likelihood. In addition, if profile_fe is true the fixed effects parameters are also profiled out.
