Hi,

Thanks for looking into this question.

I am using JMP ver 14.

I do know there is a "Prediction Interval" option as you have pointed out.

The reason I am questioning that is because, you can see the Confidence Interval calculated are two totally different value (based on 95%).

In my example:

Confidence Interval 95% caculated (based on t density function) is 22.6 to 48.1.

Confidence Interval 95% calculated (based on Poisson density function) is 32.5 to 38.4.

Due to this, it makes me wonder that the Prediction Interval option as you have shown will calculate based on the t density function rather than Poisson.

Hope this brings the question clearly now.

B.r,

Chris
