The world cotton price forecasting by using Box-Jenkins model
The ARIMA model (Autoregressive Integrated Moving Average), known also as the Box-Jenkins Model
, uses only stationary series (mean and variance are constant).
Data obtained through the Box-Jenkins model
, which were applied to develop index forecasting for trading volume of options on futures contracts, tend to show a decrease in the value question.
5]; Appendix) was formulated for the Box-Jenkins model
developed in step 2.
The Box-Jenkins model
resembles the OLS model with a few technical embellishments.
The box-jenkins model
includes several major steps.
Several statistical packages can be used for estimating the parameters of a Box-Jenkins model
using this method.
Typically, effective fitting of Box-Jenkins models
requires at least a moderately long series.
Box and Jenkins (1976) first explained the ARIMA method, and ARIMA models are frequently signified to as Box-Jenkins models
The control charts applied to the residuals of one-step-ahead forecasts based on the Box-Jenkins models
of reported cases of measles exhibited no irregular behaviour.
Still, it's nice to sit down and watch your computer do most of the thinking for you, spitting out solutions to complex Box-Jenkins models
every two seconds (if you have a built-in math coprocessor) or every thirty seconds (if you don't).
Pierce and Haugh  have shown that Box-Jenkins models
estimated for such working series will preserve the causal relationships that exist between the variables.
