The basic aims of time series analysis are the following : (1) Description: how can we describe a time series? (2) Inference: how to make inferences about the patterns in a time series, e.g., are there �cycles� in the data? (3) Prediction: use the past of a series (or several series) to predict the future. (4) Control: if we can predict the future from the past, how can we modify the current value(s) to obtain a desirable value in the future?
