Exponential distribution: Compute the Shannon, Rényi, Havrda and Charvat, and Arimoto entropies of the exponential distribution

Description

Compute the Shannon, Rényi, Havrda and Charvat, and Arimoto entropies of the exponential distribution.

Usage

Se_exp(alpha)
re_exp(alpha, delta)
hce_exp(alpha, delta)
ae_exp(alpha, delta)

Value

The functions Se_exp, re_exp, hce_exp, and ae_exp provide the Shannon entropy, Rényi entropy, Havrda and Charvat entropy, and Arimoto entropy, respectively, depending on the selected parametric values of the exponential distribution and $\delta$.

Arguments

alpha

The strictly positive scale parameter of the exponential distribution ($\alpha >0$).

delta

The strictly positive parameter ($\delta >0$) and ($\delta \ne 1$).

Details

The following is the probability density function of the exponential distribution: $$f(x)=\alpha e^{-\alpha x},$$ where $x>0$ and $\alpha >0$.
