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 regres-
sion, cubic regression, or quartic regression graph.
Example
To perform power regression using the following data and
estimate the values of and when
xi
= 40 and
yi
= 1000
