Commands When Linear Regression Calculation
(A+Bx) Is Selected
With linear regression, regression is performed in accordance
with the following model equation.
y = A + BX
The following are the commands that appear on the sub-
menus that appear when you select
 (Sum),  (Var), 
(MinMax), or
 (Reg) on the STAT menu while linear
regression is selected as the statistical calculation type.
