u1_summarized.overlap: Summarized Overlap

In MixfMRI: Mixture fMRI Clustering Analysis

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.

Examples

library(MixfMRI, quietly = TRUE)
set.seed(1234)
p <- 10  # 10 experiments.
overlap.mat <- diag(1, p)
overlap.mat[lower.tri(overlap.mat)] <- runif(p * (p - 1) / 2)
overlap.mat[upper.tri(overlap.mat)] <- t(overlap.mat)[upper.tri(overlap.mat)]
