R: Bimodality Amplitude

BimodalityAmplitude {DataVisualizations} | R Documentation

## Bimodality Amplitude

### Description

Computes the Bimodality Amplitude of [Zhang et al., 2003]

### Usage

    BimodalityAmplitude(x, PlotIt=FALSE)

### Arguments

`x` | Data vector.
`PlotIt` | FALSE, TRUE if a figure with the antimodes and peaks is plotted

### Details

This function calculates the Bimodality Ampltiude of a data vector. This is a measure of the proportion of bimodality and the existence of bimodality. The value lies between zero and one (that is: [0,1]) where the value of zero implies that the data is unimodal and the value of one implies the data is two point masses.

### Note

function was rewritten after the flow of a function of Sathish Deevi because the original function was incorrect.

### Examples

    #Example 1
    data<-c(rnorm(299,0,1),rnorm(299,5,1))
    BimodalityAmplitude(data,TRUE)

    #Example 2
    dist1<-rnorm(2100,5,2)
    dist2<-dist1+11
    data<-c(dist1,dist2)

    BimodalityAmplitude(data,TRUE)

    #Example 3
    dist1<-rnorm(210,-15,1)
    dist2<-rep(dist1,3)+30
    data<-c(dist1,dist2)

    BimodalityAmplitude(data,TRUE)

    #Example 4
    data<-runif(1000,-15,1)

    BimodalityAmplitude(data,TRUE)
