=== Distribution ===
The [[probability density function]] (pdf) of the EL distribution is given by{{cn}]
:<math> f(x; p, \beta) := \left( \frac{1}{-\ln p}\right) \frac{\beta(1-p)e^{-\beta x}}{1-(1-p)e^{-\beta x}} </math>
where <math>p\in (0,1)</math> and <math>\beta >0</math>. This function is strictly decreasing in <math>x</math> and tends to zero as <math>x\rightarrow \infty</math>. The EL distribution has [[mode|modal value]] given, at x=0, by
:<math>\frac{\beta (1-p)}{-p \ln p}</math>
