Time series analysis is the art of extracting meaningful insights from time series data by exploring the series' structure and characteristics and identifying patterns that can then be utilized to forecast future events of the series. In this chapter, we will discuss the foundations, definitions, and historical background of time series analysis, as well as the motivation of using it. Time-series analysis is a statistical method of analyzing data from repeated observations on a single unit or individual at regular intervals over a large number of observations.

Why do I care about ‘stationarity’ of a time series? Lecture 1 1.1 Introduction A time series is a set of observations xt, each one being recorded at a specific time t. Definition 1.1 A time series model for the observed data {xt} is a specifi- cation of the joint distributions (or possibly only the means and covariances) of a sequence of random variables {Xt} of which {xt} is postulated to be a realization. The theory and practice of time series analysis have developed rapidly since the appear-ance in 1970 of the seminal work of George E. P. Box and Gwilym M.
