Hi.
I've generated 20 numbers from standard normal distribution.
One sided tolerance interval for proportion of 97.5% is 2.114196.
On the othe hand, the distribution profiler shows that for 2.114196 the upper bound is 99.9959%
Am I missing something? I was thinking that the upper bound of the the distribution profiler has to be equal/approx. equal to the proportion of the tolerance interval.
I am trying to understand these numbers because of the following need.
I need to calc a tolerance interval for Gamma/Johnson distribution.
JMP does not have this option. I was thinking about distribution profiler of Gamma dist. as a solution.
Is there some way to cal a tolerance interval for Gamma/Johnson distribution?
Thank you!
