Description Functions References
dimreduce is an R package that provided functions for (supervised) dimension reduction.
Supervised PCA (SPCA) and iterative supervised PCA (ISPCA), that are useful techniques for dimension reduction. spca can also be used to compute the standard unsupervised PCA.
Function that can be used to map linear model regression coefficients fitted using latent features from SPCA or ISPCA back to the original feature space. This can be useful for analysing the model.
Functions for computing univariate relevance scores and significance tests for the features, which can be used for screening.
