u u u u u Estimated Value Calculation for Regression Graphs
The STAT Mode also includes a Y-CAL function that uses regression to calculate the
y
estimated -value for a particular
regression.
The following is the general procedure for using the Y-CAL function.
1. After drawing a regression graph, press 6(g)2(Y-CAL) to enter the graph selection mode,
and then press w.
If there are multiple graphs on the display, use f and c to select the graph you want, and
then press w.
x
• This causes an -value input dialog box to appear.
2. Input the value you want for
• This causes the coordinates for
pointer to the corresponding point on the graph.
3. Pressing v or a number key at this time causes the
so you can perform another estimated value calculation if you want.
