Hello,
I'm doing an analysis of a movement of an object in time (Position X, Y, and Z). I'm trying to do forecasting and predict ARIMA models. However, I have 3000 observations (24 per second).
I encountered two problems:
1) How to time set the time variable in my example? What I have is a specific time stamp like...4.27s, 4.28s, 4.29s... etc. and I'm not sure how to convert it properly.
2) How to calculate ARIMAs at this number of observations? 750 lags make it impossible to calculate manually.
I would very appreciate your help and suggestions.
Best,
Jacek
