bimodality_ratio: Bimodality Ratio Function

Description

This function calculates the Bimodality Ratio which is a measure of the proportion of bimodality. The proportion of bimodality here is referring to the mixture proportions of two, say, Gaussian (normal) components that can have different frequencies. For instance, a 50separation will be different from a 25results of "Example 2", "Example 3", and "Example 4" to get a better understanding.

Usage

bimodality_ratio(x, list = FALSE, ...)

Arguments

x

Data vector.

list

Calculate the Bimodality Ratio for a list of data vectors. This technique is faster than parallelizing for typical big datasets (i.e. when the length of a data vector
