survreg allows interval censored data, if that is how you want to represent measurement uncertainty. See
?Surv -----Original Message----- From: Kyle Penner [mailto:kpen...@as.arizona.edu] Sent: Tuesday, June 11, 2013 8:02 PM To: r-help@r-project.org Subject: [R] survreg with measurement uncertainties Hello, I have some measurements that I am trying to fit a model to. I also have uncertainties for these measurements. Some of the measurements are not well detected, so I'd like to use a limit instead of the actual measurement. (I am always dealing with upper limits, i.e. left censored data.) I have successfully run survreg using the combination of well detected measurements and limits, but I would like to include the measurement uncertainty (for the well detected measurements) in the fitting. As far as I can tell, survreg doesn't support this. Does anyone have a suggestion for how to accomplish this?
