R(t)
The cumulative fraction of the standard normal
distribution that lies between
t
and 0. R(t) = 1 –
t
.
Q(t)
The cumulative fraction of the standard normal
distribution that is greater than
t
. Q(t) = | 0.5–
t
|.
Regression Calculation
There are six regression options on the REG menu:
LIN
Linear Regression
y = a + b x
LOG
Logarithmic Regression
y = a + b lnx
e ^
Exponential Regression
y = a • e
bx
PWR
Power Regression
y = a • x
b
INV
Inverse Regression
y = a +
QUAD
Quadratic Regression
y = a + b x + c x
2
See Example 47~48.
1. Select a regression option on the REG menu and press [
] .
2. Press [ DATA ], select
DATA-INPUT
from the menu and press [
].
3. Enter
an
x
value and press [ ].
4. Enter the corresponding
y
value and press [ ].
5. To enter more data, repeat from step 3.
6. Press [ 2nd ] [ STATVAR ].
7. Press
[ ] [ ] to scroll through the results until you find the
regression variables you are interested in (see table below).
8. To predict a value for x (or y) given a value for y (or x), select the x ’
(or y ’) variable, press [
] , enter the given value, and press [
]
again.
Variable Meaning
a
Y-intercept of the regression equation.
b
Slope of the regression equation.
r
Correlation
coefficient.
c
Quadratic regression coefficient.
x ’
Predicted x value given a, b, and y values.
y ’
Predicted y value given a, b, and x values.
9. To draw the regression graph, press [ Graph ] on the STATVAR menu.
To return to the STATVAR menu, press [ 2nd ] [ STATVAR ].
