Automatic Regression Equation
Each regression model has an optional argument,
regequ
, for which you
can specify a
Y=
variable such as
Y
1
. Upon execution, the regression
equation is stored automatically to the specified
Y=
variable and the
Y=
function is selected.
Regardless of whether you specify a
Y=
variable for
regequ
, the
regression equation always is stored to the
TI-83 Plus
variable
RegEQ
,
which is item
1
on the
VARS Statistics EQ
secondary menu.
Note: For the regression equation, you can use the fixed-decimal mode setting
to control the number of digits stored after the decimal point (Chapter 1).
However, limiting the number of digits to a small number could affect the
accuracy of the fit.
