This ebook is a collaborative attempt from 3 workshops held over the past 3 years, all concerning primary participants to the vine-copula technique. study and functions in vines were becoming swiftly and there's now a transforming into have to collate uncomplicated effects, and standardize terminology and strategies. in particular, this instruction manual will (1) hint old advancements, standardizing notation and terminology, (2) summarize effects on bivariate copulae, (3) summarize effects for normal vines, and (4) provide an outline of its purposes. additionally, a lot of those effects are new and never available in any latest journals. New learn instructions also are mentioned.

A C-vine on five variables with constraint sets. 1. Let V = {T1 , . . , Tn−1 } be a regular vine, then (1) the number of edges is n(n − 1)/2, (2) each conditioned set is a doubleton, each pair of variables occurs exactly once as a conditioned set, (3) if two edges have the same conditioning set, then they are the same edge. 3 (m-child; m-descendant). If node e is an element of node f , we say that e is an m-child of f ; similarly, if e is reachable from f via the membership relation: e ∈ e1 ∈ · · · ∈ f , we say that e is an m-descendant of f .
