A function ##f:\mathbb{R}^3_+\to[0,1]## defined as ##f(\lambda,\beta,x)=1-e^{-\frac{\lambda}{\beta}\left(1-e^{-\beta x}\right)}## serves a lot of pain under integration.
As this function is used to describe a lower bound, could anyone suggest another non-zero function that would be smaller than ##f##?
