statsmodels.regression.mixed_linear_model.MixedLM.loglike¶
- MixedLM.loglike(params, profile_fe=True)[source]¶
Evaluate the (profile) log-likelihood of the linear mixed effects model.
- Parameters:
- params
MixedLMParams,orarray_like. The parameter value. If array-like, must be a packed parameter vector containing only the covariance parameters.
- profile_febool
If True, replace the provided value of fe_params with the GLS estimates.
- params
- Returns:
Thelog-likelihoodvalueatparams.
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.
