createLeavePersonsOutFolds: Create Leave-persons-out Folds

In gppm: Gaussian Process Panel Modeling

Create Leave-persons-out Folds

Description

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

Usage

createLeavePersonsOutFolds(gpModel, k = 10)

Arguments

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

Details

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

Value

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

See Also

Examples

data("demoLGCM")
lgcm <- gppm(
  "muI+muS*t", "varI+covIS*(t+t#)+varS*t*t#+(t==t#)*sigma",
  demoLGCM, "ID", "y"
)
theFolds <- createLeavePersonsOutFolds(lgcm)
