SOCR Analysis Example on Simple Linear Regression
This example is taken from "An Introduction to computational statistics: regression analyses" by Robert Jennrich, Prentice Hall, 1995.
As you start the SOCR Analyes Applet, click on "Simple Linear Regression" from the combo box in the left panel.
Then click on the "Example" button and then "Data" button in the right panel. You should see the data displayed in two columns. They are named as VarA and VarB here.
We'd like to use VarA as the regressor (that is, 'x', the independent variable); and use VarB as the response (that is, 'y', the dependent variable). To tell the computer which variables are assigned to be the regressor and response, we have to do a "Mapping." This is done by clicking on the "Mapping" button first to get to the Mapping Panel, and then map the variables.
