createLeavePersonsOutFolds: Create Leave-persons-out Folds
In gppm: Gaussian Process Panel Modeling

Description Usage Arguments Details Value See Also Examples

This function is used to create a leave-persons-out cross-validation fold vector to be used by crossvalidate.

1	createLeavePersonsOutFolds(gpModel, k = 10)

`gpModel`	object of class GPPM.
`k`	integer scalar. Number of folds to create.

The folds are created such that the data of each person is fully in one fold.

A fold vector, which is a vector of length nrow(datas(gpModel)) of integers from 1 to k. If foldVector[i]=j, then data point i is assigned to fold j.

crossvalidate for how to use the created fold vector to perform cross-validation.
