Summarized Overlap
Description
Compute summarized overlap on a given overlap (symmetric) matrix.
Usage
summarized.overlap(overlap.mat)
Arguments
overlap.mat |
an overlap (symmetric) matrix. |
Details
overlap.mat
is a p * p
matrix containing pair wised overlaps
of p
experiments. overlap.mat
is assumed a symmetric matrix.
This function returns a summarized overlap based on the input
overlap.mat
that charactorizes the overall overlap behavior of the
p
experiments.
Value
A single value is returned.

overlap.mat[lower.tri(overlap.mat)] <- runif(p * (p - 1) / 2)
overlap.mat[upper.tri(overlap.mat)] <- t(overlap.mat)[upper.tri(overlap.mat)]
