Model Selection by Integrated Completed Likelihood criterion
Computes the exact ICL criterion: -Loglikelihood (data,K) + H(m|K) where H is the entropy of the segmentation, and chooses the optimal number of segments as k= argmin(ICL)
An object of class EBS returned by function EBSegmentation applied to data of interest.
A vector of length Kmax giving prior probabilities on the value of K. Default value is uniform on 1:Kmax.
This function is used to compute the entropy of the segmentation in k segments (for k in 1 to Kmax) and choose the optimal K according to the ICL criteria.
An integer containing the choice of the optimal number of segments.
Vector of length x$Kmax containing the ICL values.
