Estimated Value Calculation ( , )
After drawing a regression graph with the STAT Mode , you can use the RUN
•
MAT Mode to
calculate estimated values for the regression graph's
x
and
y
parameters.
Example To perform power regression using the nearby data
and estimate the values of and when
xi
= 20 and
yi
= 1000
1. From the Main Menu, enter the STAT Mode.
2. Input data into the list and draw the linear regression graph.
3. From the Main Menu, enter the RUN
