ovl_knn: Calculate distribution overlap by KNN

In psychemistz/ovltools: Tools for estimating distribution overlap between two sample distributions

Calculate distribution overlap by KNN

Description

Calculate distribution overlap by KNN (K-Nearest neighbor) This function compares label of K-nearest neighbors and calculate how many labels are mismatch.

Usage

ovl_knn(x1, x2, k = 5)

Arguments

x1	A numeric vector.
x2	A numeric vector.
k	An integer. Number of k in KNN

Value

estimated overlap between two distributions (range: 0 to 1)
