Displaying Statistical Calculation Results
Whenever you perform a regression calculation, the regression formula parameter
(such as
a
and
b
in the linear regression
y
=
ax
+
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.
