Why Use Time Series Analysis in SPC for Excel?

SPC for Excel easily performs time series analysis using one of the above techniques. A time series is a series of data points in time order, taken at successive equally spaced points in time, such as daily, yearly, etc. A time series is plotted over time as a run chart.  There are potentially three components in a time series analysis: level, trend and seasonal.

One use of time series analysis is to forecast future values based on history.

Another objective is to find patterns in the data that can be used to extrapolate those patterns into the future.
