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
• This will display the GRAPH mode graph relation list.*1
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.
