Train model Random Forest

Description

Train model Random Forest

Usage

build.model.crossval(x, y, list.selected.var, list.index.cross, nvar)

Arguments

x	input data where columns are variables and rows are observations (all numeric)
y	decision variable as a boolean vector of length equal to number of observations
list.selected.var	A list with selected variables in cross-validation
list.index.cross	A list with indexes obtained in cross-validation
nvar	the number of first variables for which to train model Random Forest

Details

Train model Random Forest in cross-validation and variables selected in the cross-validatio

Value

A list with metrics Accuracy, AUC, MCC

                             params.cv = list(niter = 10, k = 3))

list.selected.var <- feature.selection(x = data,
                             y = class,
