overlap: Overlap Coefficient

In easystats/bayestestR: Understand and Describe Bayesian Models and Posterior Distributions

Overlap Coefficient

Description

A method to calculate the overlap coefficient between two empirical distributions (that can be used as a measure of similarity between two samples).

Usage

overlap(
  x,
  y,
  method_density = "kernel",
  method_auc = "trapezoid",
  precision = 2^10,
  extend = TRUE,
  extend_scale = 0.1,
  ...
)

Arguments

x	Vector of x values.
y	Vector of x values.
method_density	Density estimation method. See estimate_density().
method_auc	Area Under the Curve (AUC) estimation method. See area_under_curve().
precision	Number of points of density data. See the n parameter in density.
extend	Extend the range of the x axis by a factor of extend_scale.
extend_scale	Ratio of range by which to extend the x axis. A value of 0.1 means that the x axis will be extended by 1/10 of the range of the data.
...	Currently not used.

Examples

library(bayestestR)

x <- distribution_normal(1000, 2, 0.5)
y <- distribution_normal(1000, 0, 1)

overlap(x, y)
plot(overlap(x, y))
