powerPLS

This package provides a tool to perform power analysis in Partial Least Squares (PLS) for classification when two classes are analyzed.

Installation

You can install the released version of powerPLS with:

# devtools::install_github("angeella/powerPLS")
install.packages("powerPLS", repos = c('https://angeella.r-universe.dev', 'https://cloud.r-project.org'))

Quick overview

The main functions are

• computeSampleSize() which estimated the power considering several values of sample size and number of score components.

• computePower() which estimated the power considering a fixed sample size and several number of score components.

datas <- simulatePilotData(nvar = 10, clus.size = c(5,5),m = 6,nvar_rel = 5,A = 2)
out <- computePower(X = datas$X, Y = datas$Y, A = 3, n = 20, test = "R2")
out <- computeSampleSize(X = datas$X, Y = datas$Y, A = 2, A = 3, n = 20, test = "R2")
