As its name implies, CUSUM involves the calculation of a cumulative sum (which is what makes it "sequential"). Samples from a process $${\displaystyle x_{n}}$$ are assigned weights $${\displaystyle \omega _{n}}$$, and summed as follows: $${\displaystyle S_{0}=0}$$ $${\displaystyle … See more In statistical quality control, the CUsUM (or cumulative sum control chart) is a sequential analysis technique developed by E.
