sim_XY: Simulate pilot data

Description

Simulate data matrix under the alternative hypothesis with n observations by kernel density estimation

Usage

sim_XY(out, n, seed = 123, post.transformation = TRUE, A, fast = FALSE)

Value

Returns a list:

Y_H1

dependent variable, matrix with 2 columns and n rows (observations)

X_H1

predictor variables, matrix with n rows (observations) and number of columns equal to out$X (i.e., original dataset)

Arguments

out

Output from PLSc

n

Number of observations to simulate

seed

Seed value

post.transformation

Boolean value. Default to TRUE, i.e., post transformation is applied in PLSc

A

Number of score components used in PLSc.

fast

Use the function fk_density from the FKSUM R package for kernel density estimation. Default to FALSE.
