Definitions

1. In a multivariate normal distribution, the principal curves are the same as the principal components. (Web site)
2. In a multivariate normal distribution, the principal surfaces are the subspaces spanned by any two principal components. (Web site)
3. The multivariate normal distribution is the most important joint probability distribution and is the subject of Chapter 12.

Univariate Normal Distributions

1. Note that the multivariate normal distribution is not a mere composite of univariate normal distributions.

Multivariate Statistical Models

1. These topics are particularly important in multivariate statistical models and the multivariate normal distribution.

Matrix

1. If is a linear transformation of where is an matrix then has a multivariate normal distribution with expected value and variance (i.e.,). (Web site)

Inequality

1. Such an inequality for the random vectors having multivariate Normal distribution is proved.

Probability Density Function

1. Finally, a new function (mvnpdf) computes the probability density function for the multivariate Normal distribution.

Parameter Estimation

1. Parameter estimation for the multivariate normal distribution. (Web site)

Predictors

1. If the predictors are from a multivariate normal distribution, then there is far too much clustering in the centre of the design space. (Web site)

Central Limit Theorem

1. Law of large numbers, central limit theorem, generating functions, multivariate normal distribution.

Normal

1. Normal and multivariate normal distribution. (Web site)

Multivariate Analysis

1. The multivariate normal distribution provides the stochastic model on which the main theory of multivariate analysis is based. (Web site)

Multivariate Statistics

1. This distribution arises in multivariate statistics as a derivative of the multivariate normal distribution. (Web site)

Parameters

1. The Fisher information matrix for estimating the parameters of a multivariate normal distribution has a closed form expression. (Web site)

Monte Carlo Simulation

1. Monte Carlo simulation generates random market scenarios drawn from that multivariate normal distribution. (Web site)

Variables

1. The first 30 variables of x 1 follow a multivariate normal distribution with mean = 0.3.

Estimation

1. Estimation, test of hypotheses, size and power; categorical data; contingency tables; multivariate normal distribution; linear models; decision theory.
2. Densities (estimation and simulation): mvnorm() in MASS simulates from the multivariate normal distribution.

Random Vector

1. But if a random vector has a multivariate normal distribution then any two or more of its components that are uncorrelated are independent. (Web site)

Stat

1. STAT(3) = asymptotic chi-squared statistic assuming a multivariate normal distribution.

Data

1. Multivariate normality tests check a given set of data for similarity to the multivariate normal distribution. (Web site)
2. It is assumed that the data (for the variables) represent a sample from a multivariate normal distribution.

Generalized Linear Models

1. If the errors do not follow a multivariate normal distribution, generalized linear models may be used to relax assumptions about Y and U.
2. If the residual is not a multivariate normal distribution, generalized linear models may be used to relax assumptions about Y and U.

Covariance Matrix

1. The derivation of the maximum-likelihood estimator of the covariance matrix of a multivariate normal distribution is perhaps surprisingly subtle.
2. The probability distribution of the maximum likelihood estimator of the covariance matrix of a multivariate normal distribution is the Wishart distribution.
3. GLS estimates are maximum likelihood estimates when ε follows a multivariate normal distribution with a known covariance matrix. (Web site)

Multivariate Normal Distribution

1. For a sample x from a multivariate normal distribution with unknown mean and covariance matrix, test the null hypothesis that mean (x) == m. (Web site)
2. The Wishart distribution arises as the distribution of the sample covariance matrix for a sample from a multivariate normal distribution. (Web site)
3. Estimation The derivation of the maximum-likelihood estimator of the covariance matrix of a multivariate normal distribution is perhaps surprisingly subtle. (Web site)
