I create an ARIMA model for my
ts-object. My data is available in seconds or even miliseconds. I didn't find a way to specify the time information for the start- and end-parameters when creating the
I need the exact time, because I want to extract the time information when I do the forecast based on the ARIMA model to return the exact times for my forecasted values. It would be enough to store the end-time information somewhere in my ARIMA model, so that I can use it later when I do the forecast.
How is this done usually with ARIMA models?
