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!
