BVsupport: Compute the support for the cliques of a bivariate intersection graph.

Description

Given the regions where the events occurred and the cliques of the intersection graph the support of the cliques is computed. For each clique it is the intersection of the event time regions for all observations in that clique.

Usage

BVsupport(intvlx, intvly, cliques=BVcliques(intvlx, intvly))

Arguments

intvlx

The event time intervals for one dimension.

intvly

The event time intervals for the other dimension.

cliques

The list of maximal cliques of the intersection graph, optionally.

Value

An m by 4 matrix containing the corners of the intervals of support for the maximal cliques of the intersection graph corresponding to the first two arguments to the function.
