There are two zip files. The file crs-code.zip contains the R code
files, which are ASCII files in DOS format. Unix/Linux users should
use "unzip -a". The file crs-data.zip contains R data files, which are
binary files as well as their ASCII counterparts. The "-a" option
should *not* be used when unzipping this file.

## Data ##
##########

o Files: simulx1.Rdata
  Format: R Data Objects
  
  Info: x1 takes values {"1","2","3","4","5"}. They contain all
  recorded Root Average Squared Error (RASE) and execution times used in
  the numerical example in the paper in the form of two n1 x n2 x n3 x n4
  arrays called "rase" and "tiempo" respectively. n1 = 20 is the
  number of Monte Carlo replications. n2 = 2 is the RASE (in array
  "rase") and the time that command 'system.time' generates (in array
  "tiempo") when using 'npreg' {first column} and 'crs' {second
  column}. n3 = 20 is the twenty different sample sizes that are
  considered. n4=2 is the two possible error variances.

o Files: simulx1_x2.txt
  Format: ASCII file
  
  Info: x1 takes values {"1","2","3","4","5"}, and x2 takes values
  {"rase","tiempo"}. They are the ASCII version of the n1 x n2 x n3 x n4
  arrays called "rase" and "tiempo" in the "simulx1.Rdata" files
  above.

Note: No other data are used

## Software ##
##############

o Files: simulx1.R
  Format: R transcript (source code with comments)
  Application: Monte Carlo calculations.
  
  Info: x1 takes values {"1","2","3","4","5"}. The code executes all
  the Monte Carlo experiments in the paper.

o Files: graph.R
  Format: R transcript (source code with comments)
  Application: Drawing of figure.
  
  Info: This R transcript loads "simulx1.Rdata" files above (where x1
  takes values {"1","2","3","4","5"}) and draws Figure 1 in the main text.

o The software packages used to obtain the results were:
  - R system for statistical computing, version 2.14.1
    http://CRAN.R-project.org/
  - np 0.50-1
