Internal Function for Split Points for Selected Variables

This function calculate candidate splits for each selected variable. For numerical variables splits are calculated as percentiles (in general uniform quantiles of the length grid_points). For all other variables splits are calculated as unique values.

calculate_variable_split(data, variables = colnames(data), grid_points = 101)

Arguments

data	validation dataset. Is used to determine distribution of observations.
variables	names of variables for which splits shall be calculated
grid_points	number of points used for response path

Value

A named list with splits for selected variables

Note

This function is a copy of calculate_varaible_split() from ingredients package with small change.
