Jaribio la Ljung-Box Q la Uunganishaji Kiotomatiki

Jaribio la Ljung-Box Q ni jaribio la jumla (portmanteau test) lililopendekezwa na Ljung na Box (1978) ili kutathmini kama kundi la uunganishaji kiotomatiki (autocorrelations) katika mfuatano wa mabaki ya mfululizo wa muda ni sifuri kwa pamoja. Linatumika sana kutathmini utoshelevu wa mifumo ya mfululizo wa muda iliyofungwa — hasa mifumo ya ARIMA — kwa kujaribu kama mabaki yaliyobaki yanaonyesha muundo wowote wa kimfumo. Jaribio hili linatumika katika uchumi, fedha, na fani yoyote inayotegemea uundaji wa data ya muda.
