I'm consulting with a local quantitative person about some data, it's double-censored. Left censored is below limit of quantitation. Right censored is saturation of the assay. I want to regress it against a simple numeric predictor. I was just told that using survival analysis may not be appropriate because "the censoring is not independent of the outcome". Aren't so-called Tobit models also censored "independent of the outcome", but they can be run via a wrapper function in AES that just calls survreg?
I'm simply confused.
