explode_dummies: Explode dummies columns into separate dummy variables

Description Usage Arguments Value Examples

Description

This function takes a matrix with dummy outlier columns, where there are possibly multiple ones. We first merge these columns to one and then explode them to obtain one dummy variable per column.

Usage

1
explode_dummies(outlier_dummies)

Arguments

outlier_dummies

A matrix of outlier dummy variables in columns.

Value

A matrix with dummy variables in columns, each having one nonzero index. The columns are named outlier_x, with x being the 1-based row index of the position that this dummy variable is masking.
