Hi,
Is there a way to get a standard error(or 95% CI) of autocorrelation coefficient in STATA? I am using XTGEE to get autocorrelation (the code shown below). I get the result of the correlation(below) but I also want to get the standard error (or 95% CI) of each estimate. Please let me know if it is possible to do this.
Thank you,
Kayo Walsh
