MultiNormal {brms}

The Multivariate Normal Distribution

Description

Density function and random generation for the multivariate normal distribution with mean vector mu and covariance matrix Sigma.

Usage

dmulti_normal(x, mu, Sigma, log = FALSE, check = FALSE)

rmulti_normal(n, mu, Sigma, check = FALSE)

Arguments

x

Vector or matrix of quantiles. If x is a matrix, each row is taken to be a quantile.

mu

Mean vector with length equal to the number of dimensions.

Sigma

Covariance matrix.

log

Logical; If TRUE, values are returned on the log scale.

check

Logical; Indicates whether several input checks should be performed. Defaults to FALSE to improve efficiency.

n

Number of draws to sample from the distribution.
