Arima is assumed by some to be a northern land but Hesiod says only that it is a land far away from the deathless gods and mortal men. We finally talk about GARCH models to model conditional volatility in stock market returns. Note that it is applied to the residuals of a fitted ARIMA model, not the original series, and in such applications the hypothesis actually being tested is that the residuals from the ARIMA model have no autocorrelation. Autocorrelation Function (ACF) vs. It is proved that due to the introduction of MGA into the ARIMA(1,1,7) model, the MGA‐ARIMA model has the potential to be conveniently applied in every country or area by creating a parameter database used by the ARIMA(1,1,7) model. This chapter is based on the latter three. Let’s try the KPSS test on white noise with a trend but let’s use the default of stationary with no trend.
