Multivariate Normal Distribution R
a question Anybody can answer The best answers are voted up and rise to the top What is the standard error of the mean of multivariate normal distribution? up vote 0 down vote favorite Assume that the non-diagonal elements of the covariance matrix are not zero. Please provide a closed form formula. I'm interested in the bivariate case in particular. How does the formula simplify in the trivariate normal distribution bivariate case? More precisely, consider the decomposition of covariance matrix $\Sigma$ into correlation matrix $R$ and diagonal matrix $S$ that lists standard deviation: $\Sigma= S R S$. I'm interested in $S$ and $R$, when $\Sigma$ is the variance of the estimate of mean of multivariate normal distribution. mean standard-error multivariate-normal share|improve this question edited Aug 10 '15 at 15:22 asked Aug 10 '15 at 12:57 matus 458 The estimator will be a vector (since the mean of a multivariate normal distribution is a vector), so the variance of the estimator will be a matrix. When you say standard error of this estimator, do you mean the vector composed of square roots of the diagonal of this matrix? –Richard Hardy Aug 10 '15 at 14:07 Covariance matrix of the mean estimate will be always semi-positive definite symmetric matrix, no? I would like to know the full matrix. Just knowing the formula for the diagonal elements would also help. –matus Aug 10 '15 at 14:29 1 So more precisely, you need the variance-covariance matrix of the estimator, not the standard error? Then consider editing the post accordingly. –Richard Hardy Aug 10 '15 at 14:37 add a comment|

The -multivariate distribution with mean vector and covariance matrix is denoted . The multivariate normal distribution is implemented as MultinormalDistribution[mu1, mu2, ..., sigma11, sigma12, ..., sigma12, sigma22, ..., ..., x1, x2, http://mathworld.wolfram.com/MultivariateNormalDistribution.html ...] in the Wolfram Language package MultivariateStatistics` (where the matrix must be symmetric since ). In the case of nonzero correlations, there is in general no closed-form solution for the distribution function of a multivariate normal distribution. As a result, such computations must be done numerically.
