statsmodels.regression.mixed_linear_model.MixedLM.predict

MixedLM.predict(params, exog=None)

Return predicted values from a design matrix.

Parameters:

• params (array-like) – Parameters of a mixed linear model. Can be either a MixedLMParams instance, or a vector containing the packed model parameters in which the fixed effects parameters are at the beginning of the vector, or a vector containing only the fixed effects parameters.
• exog (array-like, optional) – Design / exogenous data for the fixed effects. Model exog is used if None.

Returns:

• An array of fitted values. Note that these predicted values
• only reflect the fixed effects mean structure of the model.
