multinomial: Multinomial function
In MM: The Multiplicative Multinomial Distribution
multinomial R Documentation
Multinomial function
Description
\loadmathjax
The multinomial function and its logarithm
Usage
multinomial(x)
lmultinomial(x)
Arguments
x
Numeric vector
Details
Function multinomial() returns
\mjdeqnn\choose n_1,n_2,...,n_k = \fracn!n_1!n_2!\cdots
n_k!omitted; see PDF
where \mjeqn\sum_i n_i=nn_1+...+n_k=n, and function
lmultinomial() returns the natural logarithm of this.
Note
Uses logarithmic functions to avoid overflow.

Examples
x <- runif(10)
exp(lmultinomial(x)) - multinomial(x) #should be small
