Your explanations are always very clear, thank you.

Thank you very much for this lecture. It’s really useful. I have a question about the data used for ACF and PACF - is it the detrended time series after different differencing or is it the original data ? Many thanks

Thank you very much! I have spent a long time trying to figure out how to find P,D, and Q, and you explained it very well in a short amount of time. If the series requires either one lagged differencing or seasonal differencing, do you look at ACF and PACF after carrying out those differencing?

[@SunXiaochuan-ld6jp]

Hello! Have you reached a conclusion now? I'm very confused about this because the original plot produces two additional sets of ACF/PACF plots after seasonal and non-seasonal differencing, and I don't know which set of plots(original /lag12/lag12+1d) to focus on when deciding on each parameter.
