●
Enter PredY(X) and then press to predict the Y value for the specied X value.
NOTE: In cases where more than one t curve is displayed, the PredX and PredY functions use the rst
active t dened in Symbolic view.
You can type PredX and PredY directly on the entry line, or select them from the App functions menu (under
the Statistics 2Var category). The App functions menu is one of the Toolbox menus (
).
Troubleshooting a plot
If you have problems plotting, check the following:
●
The t (that is, regression model) that you intended to select is the one selected.
●
Only those data sets you want to analyze or plot are selected in Symbolic view.
●
The plotting range is suitable. Try pressing and selecting Autoscale, or adjust the plotting
parameters in Plot Setup view.
●
Ensure that both paired columns contain data, and are of the same length.
