dT: Density function for (multivariate) t distribution

Description

Get the density of a set of samples from a t distribution

Usage

dT(x, mu, Sigma = NULL, A = NULL, df = 1, LOG = TRUE)

Arguments

x

matrix, when x is a numeric vector, it will be converted to a matrix with 1 column!

mu

numeric, mean vector.

Sigma

matrix, covariance matrix, one of Sigma and A should be non-NULL.

A

matrix, the Cholesky decomposition of Sigma, an upper triangular matrix, one of Sigma and A should be non-NULL.

df

numeric, degrees of freedom.

LOG

logical, return log density of LOG=TRUE, default TRUE.

Value

A numeric vector, the probability densities.
