robust_disc: univariate discretization based on offline change point detection

Description

Determines discretization interval breaks using an optimization algorithm for variance-based change point detection.

Usage

robust_disc(formula, data, discnum, minsize = 1, cores = 1)

Value

A tibble.

Arguments

formula

A formula of univariate discretization.

data

A data.frame or tibble of observation data.

discnum

A numeric vector of discretized classes of columns that need to be discretized.

minsize

(optional) The min size of each discretization group. Default all use 1.

cores

(optional) A positive integer(default is 1). If cores > 1, use python joblib package to parallel computation.

Examples

if (FALSE) {
## The following code needs to configure the Python environment to run:
data('sim')
robust_disc(y ~ xa, data = sim, discnum = 5)
robust_disc(y ~ .,
            data = dplyr::select(sim,-dplyr::any_of(c('lo','la'))),
            discnum = 5, cores = 3)
}
