R scripts for multivariate analysis Files

This is the script prepared to run Cubist package from R environment in a manner of 10-fold cross-validation mode. Cubist is a rule-based data analysis system. For more information please refer to its original manual at the CRAN repostitory:

http://cran.r-project.org/web/packages/Cubist/index.html

It requires data prepared in a manner of 10 pairs of training-testing datasets in tab-delimited TXT files, where the last column contains the known answer to the problem (dependent variable) and previous columns are features (regressors or independent variables). The assumption is that the model is of MISO type (multiple-input-single-output)

Script basic adjustable parameters are:

extrapolation
how much of the rules are consistent to be in the training dataset range (pwrcentages 0-100)

sample
a number between 0 and 99.9: this is the percentage of the data set to be randomly selected for model building (not for out-of-bag type evaluation).

no.committees
number of committees models

rules
number of rules for each model


Please find an example of how to run the script in the example.tar.gz archive Runs on Linux and Mac 
Windows users must get rid of multicore library
