Useful distributions

Discrete distributions

For a thourough list of discrete distributions and their properties the interested reader is referred to Wikipedia on discrete distributions.

Binomial Distribution

The binomial distribution of parameters $n \in \mathcal{N}$ and $p \in [0,1]$

$P(X=k) = {n \choose k} p^k (1-p)^{n-k}$

Poisson distribution

The poisson distribution with parameter $\lambda>0$, the intensity

$P(X=k) = \frac{\lambda^k}{k!} e^{-\lambda}$
