user_span_cutpointr {cutpointr}

Calculate bandwidth for LOESS smoothing of metric functions by rule of thumb

Description

This function implements a rule of thumb for selecting the bandwidth when smoothing a function of metric values per cutpoint value, particularly in maximize_loess_metric and minimize_loess_metric.

Usage

user_span_cutpointr(data, x)

Arguments

data

A data frame

x

The predictor variable

Details

The function used for calculating the bandwidth is 0.1 * xsd / sqrt(xn), where xsd is the standard deviation of the unique values of the predictor variable (i.e. all cutpoints) and xn is the number of unique predictor values.
