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 values for a Med-Med, quadratic
regression, cubic regression, quartic regression, sine regression, or logistic
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.
