hcp_binseg: Binary segmentation (BinSeg) method

In harbinger: A Unified Time Series Event Detection Framework

Binary segmentation (BinSeg) method

Description

Change-point detection method that focus on identify change points in mean/variance doi:10.2307/2529204. It wraps the BinSeg implementation available in the changepoint library.

Usage

hcp_binseg(Q = 2)

Arguments

Q	The maximum number of change-points to search for using the BinSeg method

Value

hcp_binseg object

Examples

library(daltoolbox)

#loading the example database
data(examples_changepoints)

#Using simple example
dataset <- examples_changepoints$simple
head(dataset)

# setting up change point method
model <- hcp_binseg()

# fitting the model
model <- fit(model, dataset$serie)

# execute the detection method
detection <- detect(model, dataset$serie)

# filtering detected events
print(detection[(detection$event),])
