) only :
C [7: Reg] [ 3 ] Quadratic coefficient C of the regression
coefficients

ˆ
x
[7: Reg] [ 4 ] Estimated value of x1
2
ˆ
x
[7: Reg] [ 5 ] Estimated value of x2
y
ˆ
[7: Reg] [ 6 ] Estimated value of y
You also can add a new data anytime. The unit automatically
recalculates statistics each time you press [ = ] and enter a new data
value.
To view or change data
1. Press [ 2nd ] [ STATVAR ] [ 2 ] to enter Editor Screen.
2. Press [
T
] or [
S
] to scroll through the data you have entered.
3. To
change
an entry, display it and enter the new data. The new
data you enter overwrites the old entry. Press [ = ] to save the
change.
4. To
delete
an entry, position the cursor on the line you want to
delete, press [ DEL ].
5. To
insert
an entry, position the cursor on the line above where
you want to insert, press [ 2nd ] [ STATVAR ] [ 3 ] and then
select [ 1 ] (Ins) to create a new blank entry, fill the new data in
the blank and press [ = ].
6. To
delete all
entries, press [ 2nd ] [ STATVAR ] [ 3 ] and then
select [ 2 ] (Del-A) to clear all data on the Editor Screen.
(Note) : Statistical data and results are retained when the
calculator is turned off, but are cleared when you change
calculation types, FREQ setting or clear data by
selecting Del-A command from STATVAR menu.
Equation Calculations
Use EQN ( [ MODE ] 3 ( EQN ) ) mode for simultaneous linear
equations calculation.
An equation type menu appears when you press [ MODE ] [3](EQN)
and enter the EQN mode. (See Example 50~51)
