mvnlikC: C++ implementation of multivariate Normal probability density function for multiple inputs

Description

C++ implementation of multivariate Normal probability density function for multiple inputs

Usage

mvnlikC(x, c, clustval, mu, sigma, loglik = TRUE)

Arguments

x

data matrix of dimension p x n, p being the dimension of the data and n the number of data points

c

integer vector of cluster allocations with values from 1 to K

clustval

vector of unique values from c in the order corresponding to the storage of cluster parameters in xi, psi, and varcovM

mu

mean vectors matrix of dimension p x K, K being the number of clusters

sigma

list of length K of variance-covariance matrices, each of dimensions p x p.

loglik

logical flag or returning the log-likelihood intead of the likelihood. Default is TRUE.

Value

a list:

• "indiv": vector of likelihood of length n;
• "clust": vector of likelihood of length K;
• "total": total (log)-likelihood;
