simulate_classes: Simulate classes

In plsVarSel: Variable Selection in Partial Least Squares

Simulate classes

Description

Simulate multivariate normal data.

Usage

simulate_classes(p, n1, n2)

simulate_data(dims, n1 = 150, n2 = 50)

Arguments

p	integer number of variables.
n1	integer number of samples in each of two classes in training/calibration data.
n2	integer number of samples in each of two classes in test/validation data.
dims	a 10 element vector of group sizes.

Details

The class simulation is a straigh forward simulation of mulitvariate normal data into two classes for training and test data, respectively. The data simulation uses a strictly structured multivariate normal simulation for with continuous response data.

Value

Returns a list of predictor and response data for training and testing.
