Finding a Regression Equation
| After you have entered the data in your data editor, set up
a scatterplot, and chosen an appropriate windown you are ready to find a
regression equation (or model) for the data. |
 |
| You need to press STAT and select CALC by using the right
cursor arrow. Press ENTER and you will paste the command on
the home screen. You need to add three items to the end of this
command. Enter L1, L2 and Y1 (under Vars, Y-vars, Function)
|
 |
| You should get the regression equation information on your
home screen.
But you should realize the data has also been put in the Y1 slot of
your equation editor.
