Example of Prediction Intervals

Suppose you are interested in computing prediction intervals for the next 10 observations of ozone level.

1.

Select Help > Sample Data Library and open Cities.jmp.

2.

Select Analyze > Distribution.

3.

Select OZONE and click Y, Columns.

4.

5.

From the red triangle next to OZONE, select Prediction Interval.

Example of a Prediction Interval Report

In this example, you can be 95% confident about the following:

•

Each of the next 10 observations will be between 0.013755 and 0.279995.

•

The mean of the next 10 observations will be between 0.115596 and 0.178154.

•

The standard deviation of the next 10 observations will be between 0.023975 and 0.069276.
