k 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
•
MAT Mode.
4. Press the keys as follows.
ca(value of xi)
K6(g)4(STAT)c( )w
The estimated value is displayed for xi = 20.
baaa(value of yi)
4(STAT)b( )w
The estimated value is displayed for yi = 1000.
