Calculating Predicted Values
The functions PREDX and PREDY will estimate (predict)
values for X or Y given a hypothetical value for the other. The
estimation is made based on the curve that has been
calculated to fit the data according to the specified fit.
To find
predicted
values
1. In Plot view, calculate the Fit (regression curve) for the
data set:
e In Symbolic view, your data set (S variable) must be
defined and checkmarked. In Symbolic Setup, the fit
type must be set,
e In Plot view, press {{FIT}} to turn on {{fiTh}} and
calculate the regression curve. (If {{FIT«}} is already
on, press it twice to make it the current regression
equation.)
2. In Home, enter PREDX (y-oo/ue) [ enter|
to find the predicted (estimated) value for the
independent variable given a hypothetical dependent
value.
® Enter PREDY ix-value) to find the predicted value of
the dependent variable given a hypothetical
independent variable.
• You can type PREDX and PREDY using the Alpha shift,
or you can copy these function names from the MATH
menu under the Stat-Two category.
