Hello,
Please, i have stationnarized times series (removing trends and seasonality using differencing) in order to find most significant lagged values for forecasting model.
Questions about PACF and ACF plots:
The PACF and ACF are for stationary time series or i need to more stationnarize data ?
Thank you.
