This model simply states that the next observation is the mean of all past observations. 2021-04-10 · A time series is a collection of observations of well-defined data items obtained through repeated measurements over time. For example, measuring the value of retail sales each month of the year would comprise a time series. This is because sales revenue is well defined, and consistently measured at equally spaced intervals. A time series database (TSDB) is a software system that is optimized for storing and serving time series through associated pairs of time (s) and value (s).

As a quasi-experimental design, ITS is an analysis of a single time-series data before and after the intervention (Bernal, et al. 2017). From the perspective of research design, ITS builds upon a rather straightforward design idea: the outcome variable would not be altered if there were no intervention.
