What is unnormalised discrete distribution?
0
$begingroup$
Can someone provide an easy to understand meaning of what unnormalized discrete distribution is and how is it different from normalized discrete distribution and when is unnormalized discrete distribution used?

My guess is when $X$ is allowed to take the values $infty, -infty$ along with a countable number of real values $x_1,x_2,...$ and $p_n=P(X=x_n)%$ then $(p_n)$ is an unnormalized discrete distribution. Note that $p_n geq 0$ and $sum p_n leq 1$ but strict inequality can occur.

Normalized means $sum p_n=1$ and unnormalized means $sum p_n<1$. But this is only a guess. I have not seen anyone using this terminology.
