WebIn Method 2, we use a "do-loop" to generate the new variables, which can be useful if your categorical variable has a large number of levels. Method 1 for creating dummy variables. compute x1 = 0. if race = 1 x1 = 1. compute x2 = 0. if race = 1 x2 = 1. compute x3 = 0. if race = 1 x3 = 1. execute. Method 2 for creating dummy variables. WebSPSS – Create Dummy Variables Tool By Ruben Geert van den Berg under SPSS Tools & Regression Categorical variables can't readily be used as predictors in multiple regression analysis. They must be split up into dichotomous variables known as “dummy variables”. This tutorial offers a simple tool for creating them. Example Data File
