density_wishart: Wishart probability density function

In fditraglia/zoofactr:

Description

Wishart probability density function

Usage

density_wishart(X, v, S, logret = FALSE)

Arguments

v	An integer, the degrees of freedom of the distribution.
S	A numeric matrix, the scale matrix of the distribution. of the variance-covariance matrix) of the distribution.
logret,	a logical value indicating whether to return the log density. Defaults to FALSE.
x	A numeric matrix, the point at which the density is to be evaluated.

Value

A column real number: the value of the probability density function by the default or the natural logarithm if logret is TRUE.

Examples

M <- matrix(c(1, 0.5, 0.5, 1), 2, 2)
density_wishart(M, 10, M)
density_wishart(M, 10, M, TRUE)
