Segmentor-class: Class "Segmentor"

In Segmentor3IsBack: A Fast Segmentation Algorithm

Description

A class for Segmentation objects.

Objects from the Class

Objects can be created by calls of the form new("Segmentor", ...).

new("Segmentor", ...):

creates a new object with class Segmentor

Slots

data:

Object of class "numeric", the vector of data

model:

Object of class "character", the assumed distribution of the data

Kmax:

Object of class "numeric", the maximum number of segments considered for the segmentation

breaks:

Object of class "matrix", the breakpoints of the optimal segmentation for each value of k

mean:

Object of class "numeric", if model = Variance, the mean used in the analysis

overdispersion:

Object of class "numeric", if model = Negative Binomial, the overdispersion used in the analysis

parameters:

Object of class "matrix", the ML estimates of the parameter of each segment of the optimal segmentation for each value of k

likelihood:

Object of class "matrix", the likelihood of the segmentation for each value of k

Cost:

Object of class "matrix", the cost of the segmentation up to point j in i segments

Pos:

Object of class "matrix", the last change-point location of the segmentation up to point j in i segments

compression:

Object of class "numeric", the value of the compression obtained prior to segmentation of the data
