Time series. In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily ...
Panel data. In statistics and econometrics, panel data and longitudinal data[1][2] are both multi-dimensional data involving measurements over time. Panel data is a subset of longitudinal data where observations are for the same subjects each time. Time series and cross-sectional data can be thought of as special cases of panel data that are in ...
A time series database is a software system that is optimized for storing and serving time series through associated pairs of time (s) and value (s). [1] In some fields, time series may be called profiles, curves, traces or trends. [2] Several early time series databases are associated with industrial applications which could efficiently store ...
The trading card game Magic: The Gathering has released a large number of sets since it was first published by Wizards of the Coast. After the 1993 release of Limited Edition, also known as Alpha and Beta, roughly 3-4 major sets have been released per year, in addition to various spin-off products. Magic has made three types of sets since Alpha ...
Cross-sectional data. In statistics and econometrics, cross-sectional data is a type of data collected by observing many subjects (such as individuals, firms, countries, or regions) at a single point or period of time. Analysis of cross-sectional data usually consists of comparing the differences among selected subjects, typically with no ...
Decomposition of time series. The decomposition of time series is a statistical task that deconstructs a time series into several components, each representing one of the underlying categories of patterns. [1] There are two principal types of decomposition, which are outlined below.

The time series refers to the data over the period, while the interruption is the intervention, which is a controlled external influence or set of influences. [1] [2] Effects of the intervention are evaluated by changes in the level and slope of the time series and statistical significance of the intervention parameters. [3]
