ppoibin: The Poisson Binomial Distribution.

In poibin: The Poisson Binomial Distribution

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)

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.

Details

See the reference for computational details.

Value

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