R Documentation
Performances of 9 methods for dimension reduction applied to 2 published real dataset
Description
This data contains two matrices: one for the Prostate dataset (from R
package lasso2) and the other for the eyedata dataset (from R package
flare). Each matrix has 5 rows and 28 colums. The columns can be
grouped as three blocs of 9 (for each method compared: LASSO, RIDGE,
Elastic net [ELNET], Stepwise variable selection [STEP], CLERE, CLERE
sparse [CLERE_s], Spike and Slab [SS], AVG method and Pairwise
Absolute Clustering and Sparsity [PACS]). The 1st 9 (1:9) contain
prediction error obtained by 5-fold cross validation using 10 random
permutation of the covariate matrix. The 2nd 9 columns (10:18)
contain the number of parameters estimated for each method. The 3rd 9
columns are times in seconds measured for fitting each methods. The 28
column is the seed utilized for generating random numbers in these
analyses. For more details, please refer the package vignette.
The R script used to create this dataset is clere/inst/doc/RealDataExample.R.
