MM (version 1.6-5)

paras: Manipulate a paras object

Description

Various utilities to manipulate paras objects. Functions pnames() and pnames<-() operate on MB objects as expected.

Usage

paras(x, p, theta, pnames = character(0))
p(x) <- value
theta(x) <- value
p(x)
theta(x)
pnames(x)
pnames(x) <- value
getVals(x)
# S4 method for paras
length(x)

Arguments

x

Object of class paras

p

In function paras(), a vector of the first \(k-1\) elements of the probabilities

theta

In function paras(), a \(k\) by \(k\) matrix with diagonal composed of ones

pnames

In function paras(), a character vector of names for the entries

value

Replacement value

Details

A paras object contains the parameters needed to specify a multiplicative multinomial distribution.

Suppose p is an object of class paras object. Then p is a list of two elements. The first element, p, is a vector of length length(p) and the second is an upper-diagonal matrix square matrix of size length(p). The vignette gives further details.

The functions documented here allow the user to inspect and change paras objects.

Examples

# NOT RUN {
jj <- paras(5)
pnames(jj) <- letters[1:5]
p(jj) <- c(0.1, 0.1, 0.3, 0.1)
theta(jj) <- matrix(1:25,5,5)
pnames(jj) <- letters[1:5]
jj

# OK, we've defined jj, now use it with some other functions:
dMM(rep(1,5),jj)
MM_single(1:5,jj)
rMM(2,9,jj)

# }
