Jump to: navigation, search

In probability theory, the Type-1 Gumbel density function is

f(x|a,b)= a b e^{-(b e^{-ax} + ax)}\,


-\infty < x < \infty.

The distribution is mainly used in the analysis of extreme values and in survival analysis (also known as duration analysis or event-history modelling).
