Segmented nestedness in binary data
A binary matrix is fully nested if its columns form a chain of subsets; that is, any two columns are ordered by the subset relation, where we view each column as a subset of the r...

Improving the analyses of nestedness for large sets of matrices
Nestedness is a property of binary matrices of ecological data and quantified by the matrix's temperature, T. The program widely used to calculate T is Nestedness Temperature...

Relationship between Non-Projective Edges, Their Level Types, and Well-Nestedness
Dependency analysis of natural language gives rise to non-projective structures. The constraint of well-nestedness on dependency trees has been recently shown to give a good fit ...

Quantifying the Degree of Self-Nestedness of Trees: Application to the Structural Analysis of Plants
In this paper we are interested in the problem of approximating trees by trees with a particular self-nested structure. Self-nested trees are such that all their subtrees of a give...
