self.belonging {PCPS}

Degree of self belonging of species

Description

Define the degree of self belonging of species.

Usage

self.belonging(dis, standardize = TRUE)

Arguments

dis

Matrix containing distance between species.

standardize

Logical argument (TRUE or FALSE) to specify if dis must be standardize in values into range 0 from 1 (Default standardize = TRUE).

Details

For the calculation of self-belonging of a set of species the dissimilarities between the species are transformed into similarities and used to define degrees of belonging to fuzzy sets (Pillar et al. 2009; Pillar & Duarte 2010). Every species among all species specifies a fuzzy set in relation to all other species, with a certain degree of belonging. The self-belonging of a given species i expresses its degree of belonging to the root node of the phylogenetic/functional tree, conditioned to the similarities between i and all other internal nodes connecting it to the root.

Value

The self-belonging for each species.
