Process capability indices (PCIs) have long served as crucial metrics in assessing the performance and quality of manufacturing processes. Recent advances in statistical estimation techniques have not ...

One of the fundamental assumptions in process capability analysis is that the process must be in statistical control. Without statistical control, the process is not predictable, the concept of a ...

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 ...
