k-factors for tolerance intervals

Created: Feb 13, 2023 08:45 AM  |  Last Modified: Jun 8, 2023 9:36 AM (12375 views)

Hi all,

the k-factor JMP uses for the upper/lower tolerance intervals are different from the ones we use in our company. Does anyone know where the k-factors of JMP are taken from? And can I get the whole k-factor tables?

I am supposed to change the tables which our company uses to the JMP tables. 

Thanks

Katharina

Hi, we use tables from statistic books. Both for one-sided and two-sided intervals. I thought that JMP does that equally. I wasn't aware that JMP calculates the k factors. I will have a look at all the formulas and at the reference documents. I still hope I can find a table, at least for the typical confidence intervals and populations we need.
