[R] [FORGED] Fitting arima Models with Exogenous Variables
good morning I am working on my project and I am fitting an SARIMAX model on my data I have a seasonal thime sereis O3 levels With 3 variables temperature, humidity and wind speed.. The O3, temperature and humidity shows a sesonal behavior, however, wind speed is stationary When I fit the model using Arima() in R.. is it correct to include the wind speed? Since it?s stationary so the model will take the seasonal difference Can you help me ? Thanks
