JMP Regression

Purpose: Suppose we wish to examine the burglary-larceny relationship using simple linear regression. The data is stored in the data file "crime.jmp".

1) To open JMP, select Start/Programs/JMP IN 4/JMP IN 4. The initial
viewing screen is the JMPIN Starter menu. To analyze an existing data file,
select Open Data Table.

2) This opens the Open Data File menu. Double-click on the folder JMP IN Data.

3) Use the slide bar to scroll to the file "Crime.JMP" found within the JMP IN Data folder.
Double-click the file.

4) Now that we've accessed the desired data file, we can run analyses.

5) To generate a scatterplot, select Analyze/Fit Y by X from the menu options at
the top of the screen. Use the Fit Y by X - Contextual menu to select the desired variables. Single-click on burglary and then the X, Factor button. Next, single-click on larceny and then the Y, Response button. Select OK.

6) A scatterplot is output.

7) Single-click the down red arrow beside Bivariate Fit of larceny By burglary. From the drop-down menu that opens, select Fit Line. Regression information is output, as desired.

7) Explore options by simply clicking on buttons. Red arrows beside headings open menus;
blue arrows collapse or open windows.

8) Simple trial and error experimentation often works well. When this is ineffective, select Help from the menu found at the top of the screen.
