WebMay 26, 2024 · We use auto arima on MA processes of orders 1,3,5 and 7. Auto_arima recognizes the MA process and its order accurately for small orders q=1 and q=3, but it is mixing AR and MA for orders q=5 and q=7. Conclusion. When you start your time series analysis, it is a good practice to start with simple models that may satisfy the use case … WebApr 30, 2024 · It means 2nd order Auto-Regressive (AR) and 3rd order Moving Average (MA). You can think it as ARIMA( AR(p), I(d), MA(q)) So the d is Integrated I(d) part that is decided based on number of times you have to do a data difference to make it stationary. We will learn more about it in the next section. What is the best way to select the value of p ...
