k Displaying the Calculation Results of a Drawn Paired-Variable Graph
Paired-variable statistics can be expressed as both graphs and parameter values. When these
graphs are displayed, the paired-variable calculation results appear as shown below when you
press 1(CALC) 1(2-VAR).
• Use c to scroll the list so you can view the items that run off the bottom of the screen.

k Copying a Regression Graph Formula to the Graph Mode
You can copy regression formula calculation results to the Graph mode graph relation list, and
store and compare.
1. While a regression calculation result is on the display (see "Displaying Regression
Calculation Results" on page 6-16), press 5(COPY).
• This will display the Graph mode graph relation list.*
2. Use f and c to highlight the area to which you want to copy the regression formula of
the displayed result.
3. Press w to save the copied graph formula and return to the previous regression calculation
result display.
