Prediction profiler confidence level change

Hello, How do you change the confidence level in the prediction profiler? Thank you, Jeff

The answer will depend on what kind of prediction profiler. If it is a prediction profiler in a Fit Model report you can change the alpha level from the red triangle menu next to Model Specification in the Fit Model dialog window.

I hope that helps but let me know if you were thinking of a prediction profiler somewhere else.

Thanks,

Phil

Gold! Thanks @Phil_Kay, that's just what I was looking for (and I've been searching for quite some time...).

Edit: Is it also possible to show the prediction interval in the Prediction Profiler of the Fit Model platform?

Edit 2: Hmm, doesn't look like it.

Yes, you would have to use the workaround that Hadley suggests:

From the red triangle at the top of the Fit Least Squares report

1. Save Columns > Prediction Formula

2. Save Columns > Indiv Confidence Limit Formula

Then

3. Graph > Profiler

4. Put all 3 saved columns into Y, Prediction Formula, and click OK

This will give the mean and upper and lower prediction limits as separate Y-axes on the profiler.

It would probably be possible to "hack" the saved StdErr Pred Formula column to use that generate confidence intervals on the profiler using this approach.
