# statsmodels.regression.mixed_linear_model.MixedLM.predict¶

MixedLM.predict(params, exog=None)[source]

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