R: Class "Segmentor"
Segmentor-class | R Documentation |
Class "Segmentor"
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
