K-Truncated Distributions

Description

Random generation for the k-truncated Poisson distribution or for the k-truncated negative binomial distribution, where “k-truncated” means conditioned on being strictly greater than k. If xpred is not one, then the random variate is the sum of xpred such random variates.

Usage

rktp(n, k, mu, xpred = 1)
rktnb(n, size, k, mu, xpred = 1)
rnzp(n, mu, xpred = 1)

Arguments

n

number of random values to return. If length(n) > 1, the length is taken to be the number required.

size

the size parameter for the negative binomial distribution.

k

truncation limit.

xpred

number of trials.

mu

vector of positive means.

Details

rktp simulates k-truncated Poisson random variates. rktnb simulates k-truncated negative binomial random variates. rnzp simulates zero-truncated Poisson random variates (maintained only for backward compatibility, it now calls rktp).

Value

a vector of random deviates.
