predict.SMSN {skewlmm}

Prediction of future observations from an smsn.lmm object

Description

Predicted values are obtained through conditional expectation. For details, see Schumacher, Lachos, and Matos (2021).

Usage

## S3 method for class 'SMSN'
predict(object, newData, ...)

Arguments

object

An object inheriting from class SMSN, representing a fitted scale mixture skew-normal linear mixed model.

newData

A data frame for which response variable should be predicted, including covariates, groupVar and possibly timeVar. If missing or NULL, fitted values are returned.

...

Value

A data frame with covariates, groupVar and ypred, where ypred contains the predicted values from the response variable.
