I'm working on the reward/renewal process question and get stuck in the following question.
could anyone please lend me some help?
-- Question:
What is the limiting distribution of excess life, when renewal lifetimes have the uniform density $f(x) = 1$, for $0<x<1$.
I know the answer is $h(x)=2(1-x)$, but I don't know how this answer came up.
