"WebThe return level plot is defined as follows. Let $G$ be the generalized extreme value distribution function, with location, scale and shape parameters $a$, $b$ and $s$ respectively. Let $z_t$ be defined by $G (z_t) = 1 - 1/t$. In common terminology, $z_t$ is the return level associated with the return period $t$. Let $y_t = -1/\log (1 - 1/t)$.
