Have a couple questions.</P> <P>&nbsp;</P> <P>In the old jump version, saw it quantile feature allowing probability number to type, it is the same as custom quantile in JUMP 17.</P> <P>Seems like there is confidence level set as default value of 0.95, having tried different numbers 0.9 or 0.99, did not see the difference in the custom quantile number.&nbsp;</P> <P>&nbsp;</P> <P>Hoping it to use to set the spec limit out of data built over a long time, can I know if Custom quantile&nbsp;@confidence level of 0.95 is good to use for it?</P> <P>&nbsp;</P> <P>Thanks in advance.</P> Fri, 08 Aug 2025 14:25:27 GMT SignalRaccoon27 2025-08-08T14:25:27Z https://community.jmp.com/t5/Discussions/Customer-quantile/m-p/893386#M105434 <P>Hello,&nbsp;</P> <P>&nbsp;</P> <P>looking for the upper and lower cut off of exponential distribution and Weibull distribution, I could find custom quantile to designate the probability.
