poibin (version 1.6)

poibin: The Poisson Binomial Distribution.

Description

The cdf, pmf, quantile function, and random number generation for the Poisson binomial distribution.

Usage

ppoibin(kk, pp, method = "DFT-CF",wts=NULL)
dpoibin(kk, pp,wts=NULL)
qpoibin(qq, pp,wts=NULL)
rpoibin(m, pp,wts=NULL)

Value

Returns the entire cdf, pmf, quantiles, and random numbers.

Arguments

kk

The values where the cdf or pmf to be evaluated.

pp

The vector for \(p_j\)'s which are the sucess probabilities for indicators.

method

"DFT-CF" for the DFT-CF method, "RF" for the recursive formula, "RNA" for the refined normal approximation, "NA" for the normal approximation, and "PA" for the Poisson approximation.

wts

The weights for \(p_j\)'s.

qq

The values where the quantile function to be evaluated.

m

The number of random numbers to be generated.
