overton_like: Overton-like subtraction of densities.

In RGLab/flowStats: Statistical methods for the analysis of flow cytometry data

Overton-like subtraction of densities.

Description

This function computes an Overton-like subtraction of two densities. It calculates the proportion of the reference density that is above a reference

Usage

overton_like(ref, test, twosided = FALSE)

Arguments

ref	The reference channel specified as a vector
test	The test (potentially positive) channel specified as a vector
twosided	boolean flag testing whether the area of the density of the test curve above the reference curve will be calculated on both sides of the mode of the test curve (TRUE) or only on the positive side of the mode (FALSE, default).

Details

The test can be one-sided or two-sided. If one sided, it tests the region of the test density that is above the mode of the reference density. If two-sided it will look at the regions on either side of the mode of the reference density. Densities are computed on a grid of 1024, and appropriately normalized.

Value

numeric value representing the proportion of the area of the test density above the reference density.
