Evaluate the probability mass function of a Multinomial distribution

Source: R/Multinomial.R
pdf.Multinomial.Rd

Please see the documentation of Multinomial() for some properties of the Multinomial distribution, as well as extensive examples showing to how calculate p-values and confidence intervals.

Usage

# S3 method for class 'Multinomial'
pdf(d, x, ...)

# S3 method for class 'Multinomial'
log_pdf(d, x, ...)

Arguments

d

A Multinomial object created by a call to Multinomial().

x

A vector of elements whose probabilities you would like to determine given the distribution d.

...

Unused. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.

Value

A vector of probabilities, one for each element of x.
