sortIntensities {ppsbm}R Documentation

Sort intensities

Description

Sort intensities associated with the estimated clustering \hat z "in the same way" as the original intensities associated with true clustering z by permutation of rows.

Usage

sortIntensities(intensities, z, hat.z, directed)

Arguments

intensities

Matrix whose rows contain piecewise constant intensities \alpha^{(q,l)}, given as a vector of values on a regular partition of the time interval.

z

Matrix of size Q \times n.

hat.z

Matrix of size Q \times n.

directed

Boolean for directed (TRUE) or undirected (FALSE) case.

Examples

# True and estimated clusters for n=6 nodes clustered into Q=3 groups
z <- matrix(c(1,1,0,0,0,0, 0,0,1,1,0,0, 0,0,0,0,1,1), nrow = 3, byrow = TRUE)
hat.z <- matrix(c(0,0,1,1,0,0, 1,1,0,0,0,0, 0,0,0,0,1,1), nrow = 3, byrow = TRUE)

# Set constant intensities for each directed pair (q,l)
intens <- matrix(c(1,1,1,2,2,2,3,3,3),9)

# Permute the rows according to the permutation that "matches" hat.z with z
sortIntensities(intens,z,hat.z, TRUE)
