CExpandWindowCluster: Window-level time series cluster expansion

Description

This is an auxillary function to expand a window-level time series cluster, based on Ciampi et al. (2010).

Usage

CExpandWindowCluster(e, Euncl)

Arguments

e

a vector of logical values identifying which time series among Euncl were clustered together with e over at least w*Epsilon slides within a window (see Definition 7 by Ciampi et al., 2010). This is a seed for window-level clustering.

Euncl

a square matrix identifying the binary window cluster relation for yet unclustered time series.

Value

Euncl should be included in the window-level cluster with e.
