Dummy Variable Regression Models 1.The nature of dummy variable In regression analysis dependent variable is influenced not only by the quantitative variables but also by the qualitative variables, such as sex, skin color, region, nationality, etc) Such variables usually indicate that the presence ...

By including dummy variable in a regression model however, one should be careful of the Dummy Variable Trap. The Dummy Variable trap is a scenario in which the independent variables aremulticollinear- a scenario in which two or more variables are highly correlated; in simple terms one variable ...
Discriminant Analysis –creates a score and if the score crosses a threshold then the dependent variable is assigned a 1. Looking at the big picture, you want your multiple regression model to: Have a good theoretical basis and; Pass the most stringent statistical tests (refer back to the sub...

Thus, when we have an intercept in the regression model and we want to avoid perfect multicollinearity, wecreate only one dummy to encode a categorical variable that has two categories. Similarly, we create dummies to encode a categorical variable that has ...

Dummy Variable Regression Output III SPSS has run and compared 2 regression models: model 1 contains working experience as the (sole) quantitative predictor. Model 2 adds our 2 dummy variables representing contract type to model 1. Adding the contract type dummies to working experience increases r...
