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:

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.

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.
