https://communities.sas.com/t5/Statistical-Procedures/Relationship-between-3-variables/m-p/698873#M33711 I have three variables volume, price and units sold. How would I go about investigating the relationship between them. <BR />I would like to use an exploratory analysis and was thinking maybe some sort of regression could work?

Principal Components is another tool that would work here.</P> <P><BR />Regression is only appropriate if you have one or more dependent variables (also called "response" variables) and one or more independent variables (also called "predictor" variables). It's not clear to me that any of your variables is a dependent variable.</P> Sat, 14 Nov 2020 14:15:31 GMT https://communities.sas.com/t5/Statistical-Procedures/Relationship-between-3-variables/m-p/698874#M33712 PaigeMiller 2020-11-14T14:15:31Z
