pair {ranktreeEnsemble}

Transform Continuous Variables into Ranked Binary Pairs

Description

The function transforms a dataset with p continuous predictors into \frac{p*(p-1)}{2} binary predictors of ranked pairs

Usage

pair(data, yvar.name = NULL)

Arguments

data

A dataset with p continuous variables or with p+1 variables including a dependent variable.

yvar.name

The column name of the independent variable in data. By default, there is no dependent variable.

Value

A data frame with the transformed data. The dependent variable is moved to the last column of the data.

Note

The function is efficiently coded in C++.
