Description
Interpretation Tools for Partial Least Squares Regression.
Description
Various kinds of plots (observations, variables, correlations, weights, regression coefficients and Variable Importance in the Projection) and aids to interpretation (coefficients, Q2, correlations, redundancies) for partial least squares regressions computed with the 'pls' package, following Tenenhaus (1998, ISBN:2-7108-0735-1).

Interpretation tools for PLS regression
morepls provides functions for the interpretation of PLS regressions.
Graphical functions :
- two-dimensional plot of observations
- two-dimensional plot of correlations between variables and components
- two-dimensional plot of variables (Y loadings and X projections)
- bar plot of regression coefficients
- bar plot of X variables weights
- bar plot of X variables VIPs
Statistical indicators :
- correlations between variables and components
- R2 and redundancies between variables and components
- Q2 and cumulative Q2 indexes
- raw and standardized coefficients
Installation
Execute the following code within R:
if (!require(devtools)){
install.packages('devtools')
library(devtools)
}
install_github("nicolas-robette/morepls")
