CuSum Class

CuSum is a cumulative sum chart. It is more efficient than a Shewhart chart for detecting small shifts in the mean of a process.

For a list of all members of this type, see CuSum Members.

Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

CuSum plots the cumulative sum of the deviations of the expected value. If $\mu_0$ is the expected mean for a process and $\bar{x}_i$ are the sample means then the cumulative sum is

$C_i=C_{i-1}+\left(\bar{x}_i-\mu_0\right)$
