Resampling Penalization for histogram selection in regression
Last updated: October, 31st 2008 - Back to index
Resampling Penalization is a family of model selection procedure by penalization that can use any exchangeable weighted bootstrap resampling scheme to compute a penalty.
It is properly defined in the general framework and extensively studied for histogram selection in regression in the following paper:
(2009) Sylvain Arlot.
Model selection by resampling penalization.

The present software allows to perform this algorithm for several examples of weights in the histogram selection case.
This code is not meant to be fast, but mainly to allow reproducibility of the results presented in the above paper.
Matlab code - version 1.0
The code requires the Statistics toolbox.
The archive contains three matlab files.
RPmodsel_hist.m is a function that performs model selection by resampling penalization among a collection of histogram models.
All the examples of weights given in the paper can be used, and the penalties can either be computed from exact formulas given in the paper or by Monte-Carlo approximation.
A demo of how to use the function RPmodsel_hist and simulate data with gener_data.m is provided with the file main.m.
