k 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 Med-Med graph and quad-
ratic regression graph.
Example To perform power regression using the following data and
estimate the values of and when xi = 40 and yi = 1000
xi (List 1) yi (List 2)
28 2410
30 3033
33 3895
