  • Matrix variate beta distribution

    In statistics, the matrix variate beta distribution is a generalization of the beta distribution. If U {displaystyle U} is a p × p {displaystyle ptimes p} positive definite matrix with a matrix variate beta distribution, and a , b > ( p − 1 ) / 2 {displaystyle a,b>(p-1)/2} are real parameters, we write U ∼ B p ( a , b ) {displaystyle Usim B_{p}left(a,bright)} (sometimes B p I ( a , b ) {displaystyle B_{p}^{I}left(a,bright)} ). The probability density function for U {displaystyle U} is:

  • Matrix variate Dirichlet distribution

    In statistics, the matrix variate Dirichlet distribution is a generalization of the matrix variate beta distribution.

  • Random variate

    In the mathematical fields of probability and statistics, a random variate is a particular outcome of a random variable: the random variates which are other outcomes of the same random variable might have different values. A random deviate or simply deviate is the difference of random variate with respect to the distribution central location (e.g., mean), often divided by the standard deviation of the distribution.

  • Control variates

    The control variates method is a variance reduction technique used in Monte Carlo methods. It exploits information about the errors in estimates of known quantities to reduce the error of an estimate of an unknown quantity.

  • Nemapogon variatella

    Nemapogon variatella

    Nemapogon variatella is a moth of the family Tineidae. It is found in almost all of Europe. It is also found in North America.

  • Antithetic variates

    In statistics, the antithetic variates method is a variance reduction technique used in Monte Carlo methods. Considering that the error reduction in the simulated signal (using Monte Carlo methods ) has a square root convergence, a very large number of sample paths is required to obtain an accurate result. The antithetic variates method reduces the variance of the simulation results.
