Re: [R] How to measure the significant difference between two time series

Q1: Quick answer a) you need to remove the seasonality - there s/b a tool in the time series package to do this - though I'm not familar enough with R to know this. b) check the resulting series to see if it is stationary - acf decays quickly i.e. within a couple of lags. c) if two series are st

Dear R experts and statisticians, I have some time series datasets, they are several years vegetation indices (about 50 data points per year) sampled from different station. These indices have similar dynamics with seasonal change. My questions are, 1) How can I compare the difference amo
