This is followe by NPSE with ARL1 = 86:33, then NPASE with ARL1 = 90:98, and finally NPSC with ARL1 = 94:90.
For this particular change in p a gain of almost 22%, 26% and 29% for the proposed NPDEWMA chart in comparison to NPSE, NPASE and NPSC charts, respectively.
The similar gains may be seen at other values of p for different combinations of n and .
