truncated: 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.

Value

a vector of random deviates.

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).
