hi, Peter:
thank you for your thoughtful response. The purpose of this exercise is to
study the relationship between response variable and predictor variable
that is numerical with some value censored. Without employing any special
techinuqes, those censored X values have to be discarded which is a waste
because they at least carry some information. I search a lot about this on
internet without much luck. I guess you are right that there is nothing
out there...
thank you again
