http://www.insight-things.com/tag/mathematical-statistics/ | An often forgotten formula for the mean of a random variable $X$ is given by:
$\displaystyle \mu=E(X)=\sum_{x=0}^{\infty} \Big(1-F(x)\Big)$
And for the continous case:
$\displaystyle \mu=E(X)=\int_{x=0}^{\infty} \Big(1-F(x)\Big)$
This blog post is going to illustrate how these formulas arise.
