Following on some previous work where we calculated the basic linear regression model in Tableau manually using calculations and Table Calculations, we can extend this a bit to allow multiple regression models. In the example below, we start with the manual calculations for various average metrics from the IPEDS higher education data set, as compared to a primary metric “Total Gross Revenue”. From here we can enable color. And from there we can have Tableau automatically calculate a new regression model based upon the color. This means we end up with one primary linear regression model, and two sub-models for elements above and below the primary model. Hope you find this useful in some manner…
