fluss_cac: FLUSS - Corrected Arc Counts

In franzbischoff/tsmp: Time Series with Matrix Profile

Description

Computes the arc count with edge correction (CAC).

Usage

fluss_cac(.mp, exclusion_zone = NULL)

Arguments

.mp	a MatrixProfile object.
exclusion_zone	if a number will be used instead of embedded value. (Default is NULL).

Details

Original paper suggest using the classic statistical-process-control heuristic to set a threshold where a semantic change may occur in CAC. This may be useful in real-time implementation as we don't know in advance the number of domain changes to look for. Please check original paper (1).

Value

Returns the input .mp object a new name cac with the corrected arc count.
