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
