| ProcessCapability Class |
Computes the process capability parameters Cp, Cpm, Cp for normally distributed data. If the data
is not normal the Box-Cox transform can be used.

TopRemarks
This standard deviation is computed using the mean of the ranges method. This
estimate is refered to the "UWAVE-R" method in the R qcc package.
