Expected waiting time until no event in $t$ years for a poisson process with rate $\lambda$

Let $T_1,T_2,\dots$ denote the exponentially distributed inter-arrival times. Each of these exceeds $t$ with probability $p=e^{-\lambda t}$. Hence the number of occurences $X$ before (but not includ …

Conditional distribution of arrival times in Poisson process

Since the inter-arrival times are independent exponentially distributed, the joint pdf of the $n$ first arrival times is \begin{align} f(t_1,\dots,t_n) &=f(t_1)f(t_2|t_1)\dots f(t_n|t_{n-1}) \\&=\la …

Poisson Distribution: Estimating rate parameter and the interval length

Let $t=T_F$. Conditional on the number of occurences $N=n$, the arrival times $t_1,t_2,\dots,t_N$ are known to have the same distribution as the order statstics of $n$ iid unif$(0,t)$ random variable …
