Model ARIMA ( Autoregresive Integrated Moving Average )

Model AR dan MA dikombinasikan menjadi model ARIMA dengan bentuk umum :

Yt = Ø0 + ØYt-1 + Ø2Yt-2 + …. ØpYt-p – W1lt-1 – W2lt-2…. Wqlt-q + ∑t

Dimana l = kesalahan ( error ) ARIMA

            Dengan penggabungan ini model dapat mengakomodasi pola data yang tdak dapat diidentifikasi secara sendiri-sendiri oleh model AR dan MA. Distribusi actual koefisien autokoreasi dan autokoreasi partial mendekati distribusi teori model ARIMA (1,0,1), karena data yang dipakai adalah data hasil pembedaan pertama model tersebut menjadi ARIMA (1,1,1) dengan notasi.

Arfican Diamod

Anecdot for african. In 1905, transport from South Africa to England posed a security problem. Detectives from London were placed on a steamboat that was rumoured to carry the stone, but this was a diversionary tactic. The stone on that ship was a fake, meant to attract those who would be interested in stealing it. The actual diamond was sent to England in a plain box via parcel post, albeit registered. www.mobilku.org
The story goes that when the diamond was split, the knife broke during the first attempt. "The tale is told of Joseph Asscher, the greatest cleaver of the day," wrote Matthew Hart in his book Diamond: A Journey to the Heart of an Obsession, "that when he prepared to cleave the largest diamond ever known, the 3,106 carats (621 g) Cullinan, he had a doctor and nurse standing by and when he finally struck the diamond and it broke perfectly in two, he fainted dead away."
