Hello everybody, I really need your help! I've got an autocorrelated time series. For each value in the time series I have a corresponding dummy variable (that can be equal to 0 or 1). I'd need to know whether or not the mean and the standard deviation of the values linked to the 0s are statistically equal or different from the ones of the values linked to the 1s. With non correlated data I would do a 2 sample t-test, but wouldn't it be not correct to do the same with an autocorrelated time series? What should I do? Thanks so much for your help!
