How to Analyze the Regression Analysis Output from Excel In a simple regression model‚ we are trying to determine if a variable Y is linearly dependent on variable X. That is‚ whenever X changes‚ Y also changes linearly. A linear relationship is a straight line relationship. In the form of an equation‚ this relationship can be expressed as Y = α + βX + e In this equation‚ Y is the dependent variable‚ and X is the independent variable. α is the intercept of the regression line‚ and β is the

Demand Forecasting Demand forecasting is the activity of estimating the quantity of a product or service that consumers will purchase. Demand forecasting involves techniques including both informal methods‚ such as educated guesses‚ and quantitative methods‚ such as the use of historical sales data or current data from test markets. Demand forecasting may be used in making pricing decisions‚ in assessing future capacity requirements‚ or in making decisions on whether to enter a new market.

The methodology of this study is use Augmented Dickey Fuller (ADF) test statistic to determine whether the variables had been used are stationary or non-stationary. Vector Auto Regression (VAR) method is apply in this study. The advantages of VAR is time series can be exhibited at the same time. The VAR methodology is revises for autocorrelation and endogeneity parametrically using vector error correction model (VECM) specification. Base on Johansen (1988; 1995)‚ the benefit of VECM is that it prevents
