loo: "Leave-one-out" approach to estimate individual network contribution

Description

Calculates the individual contribution to group network data for each subject in each group using a "leave-one-out" approach. The residuals of a single subject are excluded, and a correlation matrix is created. This is compared to the original correlation matrix using the Mantel test.

Usage

loo(resids, corrs, level = c("global", "regional"))

Arguments

resids

Data table of model residuals

corrs

List of lists of correlation matrices (as output by

level

Character string; the level at which you want to calculate contributions (either global or regional) corr.matrix). The length should equal the number of groups.

Value

A data.table with columns for
