I have a single time series, unevenly spaced. I would like to perform change point detection on it. Does it mean a non-parametric method is needed? Any pointers to which method would be valid? Also, it has only 70 data points. The 'change point' package in R implements PELT, SegNeigh & BinSeg, any opinions?
