Computes the variance of the modified logarithmic series distribution
ModLSD_Var(delta, p)parameter \(\delta\) of the modified logarithmic series distribution
parameter of the modified logarithmic series distribution
Mean of the modified logarithmic series distribution
A random variable \(X\) has modified logarithmic series distribution with parameters \(0\le \delta <1\) and \(0<p<1\) if \(P(X=0)=(1-\delta)\) and $$P(X=x)=(1-\delta)(-1)/(\log(1-p))p^x/x, \mbox{ for } x=1,2,\dots.$$
