cdf: cdf

In cynzajac/CZPoisson: CZPoisson R Package

Description

cdf calculates the cumulative probability function for the Poisson distribution.

Usage

cdf(x, lamb, lower.tail = TRUE, log.p = FALSE)

Arguments

x	vector of quantiles
lamb	vector of non-negative means for Poisson distribution
lower.tail	logical; if TRUE, computes the probability of observing count less than or equal to x. If FALSE, computes the probability of observing a count greater than x
log.p	logical; if TRUE, returns log of cumulative probability of x. If FALSE, returns the cumulative probabilities of x

Details

cdf uses the cumulative probability function of gamma distribution

1/Γ(floor(x)+1) * γ(floor(x)+1,λ)

cdf(123456789, 123456789)

# Upper tail probability
cdf(5, 5:10, lower.tail = FALSE)
