[R] random truncation

What do you mean "What integral?"...
The integral on the Wikipedia page.
(The same page referenced in the earlier posts).

Seems quite obvious to me...
Did you read the Wikipedia page?

Numerical methods have been around for a while...

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.
