Difference Excel addin-in for change point analysis to detect shift in process mean

Change Point Analysis

In today’s environment, we are often buried under data ranging from sales and production figures to absenteeism and accident rates. Fundamental questions we try to answer when we look at a key performance indicator or historical data are: Did changes occur? When? What was their amplitude? Are we improving our performance? Are we sure?

The change point analysis, a versatile tool minimally affected by outliers, can analyze almost any kind of data. It identifies the moment a shift in mean was observed, the magnitude of the shift and the probability the shift is not a ‘real’ shift but just a pattern observed by chance.

Read this short article to learn more about change point analysis.
