The concept of > "random truncation" is quite precisely defined. I wasn't referring the problem of "random truncation". I was referring to the original post. In particular, how Y, S[i] and d[i] are defined. Maybe, I should be more precise when suggesting others be more precise. (My bad). I note that Spencer has posted again. I will read the new post, later, when I get some more time.
