In mathematics , a univariate object is an expression , equation , function or polynomial involving only one variable . Objects involving more than one variable are multivariate . In some cases the distinction between the univariate and multivariate cases is fundamental; for example, the fundamental theorem of algebra and Euclid's algorithm for polynomials are fundamental properties of univariate polynomials that cannot be generalized to multivariate polynomials.
2-413: Multivariate is the quality of having multiple variables. It may also refer to: Multivariate (mathematics) In statistics , a univariate distribution characterizes one variable, although it can be applied in other ways as well. For example, univariate data are composed of a single scalar component. In time series analysis , the whole time series is the "variable": a univariate time series
4-412: Is the series of values over time of a single quantity. Correspondingly, a "multivariate time series" characterizes the changing values over time of several quantities. In some cases, the terminology is ambiguous, since the values within a univariate time series may be treated using certain types of multivariate statistical analyses and may be represented using multivariate distributions .
