\name{dmvt} \alias{dmvt} \title{Density of the Multivariate t Distribution with Box-Cox Tranformation} \description{ This function computes the densities at the inputted points of the multivariate \eqn{t} distribution with Box-Cox transformation. } \usage{ dmvt(x, mu, sigma, nu, lambda, log=FALSE) } \arguments{ \item{x}{A matrix or data frame of size \eqn{N \times P}{N x P}, where \eqn{N} is the number of observations and \eqn{P} is the dimension. Each row corresponds to one observation.} \item{mu}{A numeric vector of length \eqn{P} specifying the mean.} \item{sigma}{A matrix of size \eqn{P \times P}{P x P} specifying the covariance matrix.} \item{nu}{The degrees of freedom used for the \eqn{t} distribution. If \code{nu=Inf}, Gaussian distribution will be used.} \item{lambda}{The Box-Cox transformation parameter. If missing, the conventional \eqn{t} distribution without transformation will be used.} \item{log}{A logical value. If \code{TRUE} then the logarithm of the densities is returned.} } \value{ A list with the following components: \item{value}{A vector of length \eqn{N} containing the density values.} \item{md}{A vector of length \eqn{N} containing the Mahalanobis distances.} } \author{ Raphael Gottardo <\email{raph@stat.ubc.ca}>, Kenneth Lo <\email{c.lo@stat.ubc.ca}> } % \examples{ % % } \keyword{distribution}
