bhattacharyyaCoefficient {LymphoSeq}R Documentation

Bhattacharyya coefficient

Description

Calculates the Bhattacharyya coefficient of two samples.

Usage

bhattacharyyaCoefficient(sample1, sample2)

Arguments

sample1

A data frame consisting of frequencies of antigen receptor sequences. "frequencyCount" is a required column.

sample2

A data frame consisting of frequencies of antigen receptor sequences. "frequencyCount" is a required column.

Value

Returns the Bhattacharyya coefficient, a measure of the amount of overlap between two samples. The value ranges from 0 to 1 where 1 indicates the sequence frequencies are identical in the two samples and 0 indicates no shared frequencies.
