If you do not specify both LSL and USL, the variable _CP_ is assigned a missing value. The process capability index C pk is computed as If you specify only USL, the index C pk is computed as You can ...

A review of the four basic process capability indices has been made. The interrelationship among these indices has been highlighted. Attention has been drawn to their drawbacks. The relation of these ...

Standard capability indices such as C pk are generally considered meaningful only if the process output has a normal (or reasonably normal) distribution. In practice, however, many processes have ...
