Definitions for "Univariate"
statistical tests for comparing two or more groups; techniques include t-test, analysis of variance, sign test, Wilcoxan rank test, and the Mann-Whitney U-test
This is the situation where one type of quantity is, or assumed to be, uncorrelated with another. Meteorological variables are rarely uncorrelated with each other (the multivariate case), but sometimes new variables are chosen that are approximately uncorrelated. This is part of the preconditioning procedure.
Involving only one variable.
A random variable with a numerical value that is defined on a given sample space
A discrete choice model in which the choice is made from a one-dimensional set is said to be a univariate discrete choice model. Source: econterms
