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 ...
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 ...
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 ...
