For a thorough analysis, however, we want to make sure we satisfy the main assumptions, which are. Using SPSS for regression analysis Let us assume that we want to build a logistic regression model with two or more independent variables and a dichotomous dependent variable ( if you were looking at the relationship between a single variable and a dichotomous variable, you would use some form of bivarate analysis relying on contingency tables ). If you mean the latter, then you can use the nestreg prefix command with regress to carry out hierarchical linear regression. <>/ProcSet[/PDF/Text]>>/StructParents 4/Tabs/S>> We will use the data file . endobj Add sales as your dependent variable. If you perform a hierarchical regression, the corresponding values of the "collinearity diagnostics" table appear separately for each regression step ("Model 1", "Model 2"): I would primarily interpret the data for the last step or, in general, the data for those steps that you report and interpret for your hypothesis tests in … Stepwise regression essentially does multiple regression a number of times, each time removing the … <>stream %���� We are now going to perform a regression as usual. 14 0 obj endobj endobj <>/XObject<>/ProcSet[/PDF/Text/ImageC]>>/StructParents 12/Tabs/S>> <> ÉèUÐ"&LÎê+'údsfÜCéZÕ_%nï´#Þ tM9ú5YvÅn6¨h³®À_x©ÊÖ ®K;o9P¨Ê"õ >+û¤ûùôÒXYV¥» The variable we want to predict is called the dependent variable (or sometimes, the outcome, target or criterion variable).
