PERAMALAN JUMLAH MAHASISWA BARU DENGAN MODEL AUTOREGRESSIVE INTEGRATED MOVING AVERAGE (ARIMA)
Abstract
Model ARIMA yang digunakan adalah model ARIMA (2,2,1) dan ditulis sebagai berikut:
(1+0.7795 B + 0.6484 B2 ) (1-B )2 Yt = (1 – 0.8575B) at
dimana, p (B) = (1 - 1B1 - 2B2- …- pBp), Φp (B) = (1 - Φ1B1 - Φ2B2- …- ΦpBp), Yt = data at = error
Dari model ini diketahui bahwa data sekarang tergantung dari data dua periode yang lalu dan errornya tergantung dari satu periode yang lalu. Model ini mempunyai nilai mean square error (MSE) sebesar 446,22.
Hasil dari penelitian ini dapat dipakai sebagai salah satu acuan dalam perencanaan proses belajar mengajar oleh pihak kampus.
