UninetEngine

Uninet standalone

Uninet is a standalone uncertainty analysis software package. Its main focus is dependence modelling for high dimensional distributions. Random variables can be coupled using Bayesian networks, vine-copula constructions or dependence trees.

UninetEngine library

Besides the Uninet application and its GUI, the functional core library UninetEngine can be used directly. The UninetEngine COM library is an extensive, object oriented, language-independent library containing over 70 classes with over 500 methods (functions).

The library can be used from a wide variety of programming languages: C++, C#, VB.net, Delphi, Matlab, R, Octave and VBA (as used by e.g. Excel) are a few languages in which frameworks using UninetEngine have been or are being written.

Several extra facilities are accessible through the programmatic interface, such as different samplers (e.g. the extremely fast pure memory sampler) and different ways of quantifying a Bayesnet (e.g. the arc correlations can be specified via a correlation matrix).
