sorensenMat: Sorensen similarity Matrix for bicluster output

Description

Computes Sorensen similarity matrix for biclusters in two bicluster sets

Usage

sorensenMat(x, y, type=c("rows", "cols", "both"))

Arguments

x

BiclustSet object containing row and column indicators of bicluster membership, number of biclusters

y

BiclustSet object containing row and column indicators of bicluster membership, number of biclusters

type

whether to compute Sorensen index in two dimensions, row dimension or column dimension

Value

matrix of pairwise Sorensen indices

Details

This function operates on BiclustSet objects and computes pairwise similarity based on the common elements between biclusters. Sorensen similarity score \(so\) for two biclusters A and B is computed as $$so = \frac{2|A\cap B|}{|A| + |B|}$$
