Copying A Regression Graph Formula To The Graph Mode - Casio CFX9850GBPLUS User Manual

Calculating and Graphing Paired-Variable Statistical Data
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 (2VAR).
• 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 6-3-5), 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.
* 1 You cannot edit regression formulas for graph
formulas in the GRAPH mode.
