Use the radio buttons to specify the way to quantify the number of observations to hold out.

Available methods for quantifying the number of observations to hold out are described in the table below:

Method	Description
K for K-Fold or 1/K	K = The number of folds or Groups in a partition
L for Leave-L-Out	L = The number of observations to leave out
P for P-Percent-Hold-Out	P = The percentage of observations to hold out

Note: If N is the number of observations, then 1/K = L/N = P/100.
