"WebConditional Galton–Watson trees were ﬁrst studied by D. P. Kennedy [15] and a key correspondence was found between oﬀspring distributions of conditional Galton–Watson trees and certain families of “simply-generated trees” [20]: i) When ξ ∼ Binomial(k,1/k), the conditional Galton–Watson tree is a k-ary tree.
