Implementing interval censoring in analysis

VoidBender — Thu, 27 Jun 2024 15:08:33 GMT

Hello,

I have recently watched the following JMP video for representing censored data, and I am using JMP Pro 16.

https://community.jmp.com/t5/Discovery-Summit-Americas-2023/Well-Not-Exactly-An-Introduction-to-Censored-Data-Analysis-2023/ta-p/651696

My data is left censored, but the detection limit is not constant so I believe the only way to appropriately represent this censoring is the two-column method. I would like to use it, but while this video and other sources I've found may describe how to represent the censoring in two columns, none that I have found explain how to enter them into an analysis to be properly treated as interval-censoring. I've tried simply adding both columns into the response window, but for some analyses it pops up a warning about missing values in one of the responses, others it doesn't, and I doubt the results I've gotten in each case.

Would someone be kind enough to show an example of implementing such an analysis through the JMP GUI?

Thank you
