Question

A retail store aiming to forecast its monthly sales for the upcoming year could benefit from using the ARIMA (AutoRegressive Integrated Moving Average) model. This method is well-suited for time series data, where patterns such as trends, seasonality, and autocorrelation are common. ARIMA works by combining autoregression (AR), differencing (I), and moving averages (MA) to model the time-dependent structure of the data. It is particularly useful when the data shows a trend or seasonal pattern, which is often the case in retail sales due to factors like holidays or promotions. One of ARIMA's main strengths is its ability to provide a flexible approach that can model various types of time series behaviors, such as random fluctuations and systematic patterns. It is particularly advantageous in situations where past values are highly predictive of future outcomes, as it relies on the historical data of the series to make predictions.
