Chati ya Udhibiti ya EWMA

Chati ya udhibiti ya wastani unaohama kwa nguvu (EWMA), iliyoanzishwa na S. W. Roberts mwaka 1959, inafuatilia mchakato kwa kutumia wastani wenye uzito ambao unatoa uzito mkubwa zaidi kwa uchunguzi wa hivi karibuni huku ukiruhusu uchunguzi wa zamani kufifia kijiometri. Kama CUSUM, kumbukumbu hii inaufanya uwe na ufanisi sana katika kugundua mabadiliko madogo, yanayoendelea katika wastani wa mchakato, na kigezo kimoja cha ulainishaji λ kinachodhibiti ni kiasi gani cha taarifa za zamani ambacho chati huhifadhi.
