Cpk cmk ratio
WebCg and Cmk are calculated the same as Cp and Cpk (respectively). QI Macros uses uses “Cp” and “Cpk” as the default names. And although the calculations are the same, the difference is in the methodology of … WebIk > 3 (i.e. Cmk, Cpk > 1). Yet again, non-central t is not a standard facility on most statistical software. For these reasons, a simple approximate method is highly desirable. By virtue of the independence of x and s (or x and (X) we may also regard L - x and s as independent, so that Ik becomes the ratio of two independent variables. For the
