The Categorical Distribution

Description

Density and random generation for the categorical distribution

Usage

dcat(x, prob, log = FALSE)

rcat(n = 1, prob)

Arguments

x	non-negative integer-value numeric value.
prob	vector of probabilities, internally normalized to sum to one.
log	logical; if TRUE, probability density is returned on the log scale.
n	number of observations.

Details

See the BUGS manual for mathematical details.

Value

dcat gives the density and rcat generates random deviates.
