Using (Sn)‎ estimator in the process capability indices and comparison with (MAD)‎ in the process capability indices

الملخص EN

Scale estimators are very important in many statistical applications.

A robust estimator is an estimator which is insensitive to changes in the underlying distribution and also resistant against the presence of outliers.

Several authors have worked on robust control charts and several robust measures are experimented in process control.

In this paper proposes the determination of the common process capability indices based on the (Sn) and compared with (MAD) in the Process Capability Indices to justify the efficiency and sensitively.
