WebIn statistics, the multivariate t-distribution (or multivariate Student distribution) is a multivariate probability distribution. It is a generalization to random vectors of the Student's t -distribution, which is a distribution applicable to univariate random variables. WebThe normal distribution assumes that the population standard deviation is known. The t- distribution does not make this assumption. The t- distribution is defined by the …
