Multiple Regression

Multiple Regression. In the previous section, we examined simple regression , which has just one independent variable on the right side of the equation. In this section, we consider multiple regression, in which there are two or more independent variables on the right side of the equation.

We use the identity

Which conditions should the expected cointegration mean satisfy?. Generally we would like the mean of an equilibrium error to be equal to zero!. We use the identity. The case with a constant and a trend. When there is a linear time trend in the equations, then:. A simulated example.

7 Dummy Variables

7 Dummy Variables. Thus far, we have only considered variables with a QUANTITATIVE MEANING -ie: dollars, population, utility, etc. In this chapter we will cover variables with a QUALITATIVE meaning -ie: gender, location, race, specific knowledge or attribute. 7. Dummy Variables.
