new observations for the functional predictors. It is a list of length \(p\), the number of functional predcitors. Each element is the observed matrix from a functional predictor, with rows repsenting observation vectors and columns corresponding to the observation time points.
Value
A matrix containing the predicted response for the new
observations. The number of rows is equal to the sample size of the
new data set, and the number of columns is equal to the length of
t.y.test or t.y when t.y.test=NULL.
