ARIMA and Seasonality

Seasonality in ARIMA models refer to presence of repeating patterns or
cycles of fixed lengths within time series data. In order to model the
seasonality of a time series, seasonal differencing is applied to the data.
Akaike Information Criterion (AIC) is used as part of performance metrics
to measure the goodness of fit of the models. The models are also
validated with in-sample CV and out-of-sample data to ensure the model
is not over fitted.
