ModLSD_Var {trawl}R Documentation

Computes the variance of the modified logarithmic series distribution

Description

Computes the variance of the modified logarithmic series distribution

Usage

ModLSD_Var(delta, p)

Arguments

delta

parameter δ\delta of the modified logarithmic series distribution

p

parameter of the modified logarithmic series distribution

Details

A random variable XX has modified logarithmic series distribution with parameters 0δ<10\le \delta <1 and 0<p<10<p<1 if P(X=0)=(1δ)P(X=0)=(1-\delta) and

P(X=x)=(1δ)(1)/(log(1p))px/x,\mboxforx=1,2,.P(X=x)=(1-\delta)(-1)/(\log(1-p))p^x/x, \mbox{ for } x=1,2,\dots.

Value

Mean of the modified logarithmic series distribution
