k Displaying Statistical Calculation Results

Whenever you perform a regression calculation, the regression formula parameter (such as

b

) calculation results appear on the display. You can

use these to obtain statistical calculation results.

Regression parameters are calculated as soon as you press a function key to select a
regression type while a graph is on the display.
