u To perform residual calculation
1. Perform steps 1 and 2 under "To view regression calculation results" (page 138).
2. On the dialog box that appears, tap the [Copy Residual] down arrow button, and then select [On] or the list
into which you want to copy the residual values.
3. Tap [OK].
• This assigns residual data to a system variable named "residual" (and also to the list if you specify a list in
step 2).
• Values assigned to the "residual" system variable shows the vertical distances between actually plotted
points and the regression model. A positive value indicates a plot that is higher than the regression model,
while a negative value indicates a plot that is lower.
You can use the following procedure to view the current "residual" system variable values.
1. On the Stat Editor window, select any cell in the column where you want the list you will open to appear and
then tap [Edit] - [Open List].
2. Enter "residual", and then press E.

Performing Test, Confidence Interval and Distribution Calculations Using the Wizard

ClassPad includes built-in commands* for performing test, confidence interval, and distribution calculations.
The Statistics application lets you perform these types of calculations by simply inputting values and specifying
required information in accordance with instructions displayed by a wizard. This eliminates the need to input
commands and their arguments directly.
* For information about command syntax, see "12-4 Program Command Reference".
u ClassPad Operation
1. On the Stat Editor window, tap [Calc] and then tap [Test], [Interval], [Distribution] or [Inv. Distribution].
• This displays the Wizard window in the lower half of the screen.
• Selecting the [Help] check box causes the Wizard window to fill the display, and displays the description of
the command.
* Including test, confidence interval and distribution calculations.
