Hi,I would like to plot autocorrelagram, using descriptive analysis feature. However, I would like to know that how to determine a proper number of lag.In addition, I have totally of 1241 observations, and according to the XLSTAT software, it asked me for the number of lag, then I selected automatic. Accordingly, I got 31 lags.How this number, 31, come? and Are there any other criteria to determine the most appropriate number of lag?Thank youThomas
This number equals 10*log10(n). N being the number of observations.
