uniMaxScoreSplit: Univariate score maximizing splitting

In AssocBin: Measuring Association with Recursive Binning

Univariate score maximizing splitting

Description

A function which splits a bin based on the location maximizing a score function.

Usage

uniMaxScoreSplit(bin, scorer, minExp = 5)

Arguments

bin	a bin to be split with elements 'x', 'y', 'depth', 'bnds' (list with elements 'x' and 'y'), 'expn', 'n'
scorer	function which accepts a numeric vector of potential split coordinates and the bounds of 'bin' and returns a numeric vector of scores for each
minExp	numeric giving the minimum expected count allowed in a bin

Details

This function is the univariate version of 'maxScoreSplit' and so is considerably simpler. It assumes the variable to be split is named 'x' in the bin, and the other variable is to remain unsplit.

Value

A list of two bins resulting from the split of 'bin' at the maximum split location along y
