Having some trouble figuring out this problem. Say you have a counting process $N_t$ where the rate is a random variable $\Lambda$ which is exponentially distributed with rate $\alpha$. I'm trying to find the unconditional PMF of $N_t$, as well as the conditional expectation of $\Lambda$ given $N_t$ and the first $n$ arrival times (i.e. $E(\Lambda | N_t = n, S_1 = s_1, ... , S_n = s_n)$). I'm hoping this would maybe be easier to figure out once I'm able to figure out the unconditional PMF of $N_t$. Any help is appreciated!
