What is the correct way of interpreting a changepoint graph? Here is what R gives for changepoint analysis of the mean of a data set:
---------- Changepoint type : Change in mean Method of analysis : AMOC Assumed Distribution : Normal Type of penalty : SIC with value, 4.770685 Maximum no. of cpts : 1 Changepoint Locations : 15 118
So changes occurred at t=15 and t = 118?
