LindleyBinomial

Description

distribution function, density function, hazard rate function, quantile function, random number generation

Usage

Arguments

vector of positive quantiles.

lambda

positive parameter

theta

positive parameter.

m

number of trails.

logical; If TRUE, probabilities p are given as log(p).

p

vector of probabilities.

n

Details

Probability density function

f(x)=\frac{\theta\lambda^2}{(\lambda+1)A(\theta)}(1+x)exp(-\lambda x)A^{'}(\phi)

Cumulative distribution function

F(x)=\frac{A(\phi)}{A(\theta)}

Quantile function

F^{-1}(p)=-1-\frac{1}{\lambda}-\frac{1}{\lambda}W_{-1}\left\{\frac{\lambda+1}{exp(\lambda+1)}\left[\frac{1}{\theta}A^{-1}\{pA(\theta)\}-1\right]\right\}

Hazard rate function

h(x)=\frac{\theta\lambda^2}{1+\lambda}(1+x)exp(-\lambda x)\frac{A^{'}(\phi)}{A(\theta)-A(\phi)}

where W_{-1} denotes the negative branch of the Lambert W function. A(\theta)=\sum_{n=1}^{\infty}a_n\theta^{n} is given by specific power series distribution. Note that x>0, \lambda>0 for all members in Lindley Power Series distribution. 0<\theta<1 for Lindley-Geometric distribution, Lindley-logarithmic distribution, Lindley-Negative Binomial distribution. \theta>0 for Lindley-Poisson distribution, Lindley-Binomial distribution.

Value
