~~ Methods for function logLik ~~
signature(object = "cpt")Returns the -2*log-likelihood of the data with the fitted changepoints, two values are returned, the raw twice negative log-likelihood and twice negative log-likelihood + penalty. Only valid for cpttype="mean","variance" or "mean and variance".
set.seed(1) x=c(rnorm(50,0,1),rnorm(50,0,10),rnorm(50,0,5),rnorm(50,0,1)) out=cpt.var(x,penalty="Manual",pen.value="2*log(n)",method="BinSeg",Q=5) logLik(out) # returns the raw scaled negative likelihood (925.8085) and the scaled negative #likelihood + penalty (957.5984)
