The sequential probability ratio test, or SPRT, can be used as an efficient tool for process tolerance and mean shift determinations. It also provides for simplifying insights into the nature of random mean shifts when process tolerances and Type I/II errors are selected. The cumulative sum design of the test naturally compensates for random errors, […]

The power of the test is the measure of how good a hypothesis test is. A “good” test should reject a null hypothesis when it is false and accept it when it is true.
