Estimated Value Calculation ( , )
After drawing a regression graph with the
STAT Mode
, you can use the
RUN
Mode
to calculate estimated values for the regression graph's
x
and
y
parameters.
• Note that you cannot obtain estimated value for a Med-Med, quadratic
regression, cubic regression, quartic regression, or sine regression graph.
Example
To perform power regression using the
nearby data and estimate the values of
and when
xi
= 40 and
yi
= 1000
1. In the Main Menu, select the
STAT
icon and enter the STAT Mode.
2. Input data into the list and draw the power regression graph*.
3. In the Main Menu, select the
RUN
icon and enter the RUN Mode.
4. Press the keys as follows.
