dot-withness: Identify data split that minimizes variance

In cornelmpop/Lithics3D: A toolbox for 3D analysis of archaeological lithics

Identify data split that minimizes variance

Description

This function evaluates a numeric vector to determine the split point that minimizes the within-group variance.

Usage

.withness(x)

Arguments

x	A numeric vector containing the data to be analyzed.

Details

This is a translation of c++ code from the Meshlab Virtual Goniometer plugin developed by the AMAAZE consortium

Value

A list containing the following components:

• w: The minimum within-group sum of squares (variance) for the optimal split.

• m: The value at the optimal split point in the sorted data.

• mlow: The lower boundary value of the primary cluster around the split point.

• mhigh: The upper boundary value of the primary cluster around the split point.

Examples

## Not run: 
data <- rnorm(100)
result <- Lithics3D:::.withness(data)
print(result)

## End(Not run)
