Dear all,
I have an annual time-series of population numbers and I would like to estimate the auto-correlation. Can I use acf() function and judge whether auto-correlation is significant by the plots? The acf array, eg: Autocorrelations of series 'x$log.s.r', by lag 0 1 2 3 4 5 6 7 8 9 10 11 12 1.000 0.031 -0.171 -0.451 0.021 0.070 0.238 -0.079 -0.046 0.006 0.188 -0.134 -0.016 13 14 15 -0.153 0.146 0.096 gives the auto-correlation at lags 1, 2.... Is that right? Thank you!
