The main objective of this project Work is to
introduce a method of analysis that will be used to construct a mathematical
model. The box-Jenkins methodology vas used in this study which applies ARIMA
(autoregressive integrated moving average) to find the best fit for the time
series observations in order to make reliable forecasts. However, SARIMA (1 1
2) (2 I 2) was selected as the appropriate mathematical model for the series
and the required model are given ns: Y=O.881 + O.8904ef _12+ O.9719e_21. +
O.1263eT_12—4185et _2+ - 0.5829Y_13
+ 12 — 0.2O51Y-12+ ftS829Y_13+ 0.2051Y _2 1--
0.85O1Y_24+ 0.8501Y 36. The box-pierce or Q-statistic.:, proposed b
lox and Pierce (1970), was used to check the residuals for evidence of auto
correlation.
