In dwinter/mdm: Mixtures of Dirichelet-Multinomial Distributions

Description

Calculate the likelihood of a given mixture of Dirichelet Multiomials model

Usage

dmdm(x, phi = NULL, scale = NULL, p = NULL, f, log = TRUE)

Arguments

phi	overdispersion paramater. Value must be in [0,1], where phi=0 is 'pure' Multinomial distribuion and increasing values of phi lead to increasingly over-dispersed distributions.
scale	Scale parameters, vector of matrix.
p	matrix or vector of proportions
f	mixture proportions
log	logical if TRUE (default) return the log likelihood

Value

ll numeric the (log)-likelihood given by the paramaters and data

w numeric matrix with the probabilities that a given observation is belongs to a model-component in f
