Measurement and partitioning of diversity, based on Tsallis entropy, following Marcon and Herault (2015) <doi:10.18637/jss.v067.i08>.
  'divent' provides functions to estimate alpha, beta and gamma diversity of communities, including phylogenetic and functional diversity.

A suite of 'loon' related packages providing data analytic tools for 
    Direct Interactive Visual Exploration in R ('diveR').
    These tools work with and complement those of the 'tidyverse' suite, 
    extending the grammar of 'ggplot2' to become a grammar of interactive
    graphics.
    The suite provides many visual tools designed for moderately (100s of variables)
    high dimensional data analysis, through 'zenplots' and novel tools in 'loon', and
    extends the 'ggplot2' grammar to provide parallel coordinates, Andrews plots, and arbitrary 
    glyphs through 'ggmulti'.
    The  'diveR' package gathers together and installs all these related packages
    in a single step.

Compares the fit of alternative models of continuous trait differentiation between sister species and other paired lineages. Differences in trait means between two lineages arise as they diverge from a common ancestor, and alternative processes of evolutionary divergence are expected to leave unique signatures in the distribution of trait differentiation in datasets comprised of many lineage pairs. Models include approximations of divergent selection, drift, and stabilizing selection. A variety of model extensions facilitate the testing of process-to-pattern hypotheses. Users supply trait data and divergence times for each lineage pair. The fit of alternative models is compared in a likelihood framework.

Diversification is one of the most important concepts in portfolio management. This framework offers scholars, practitioners and policymakers a useful toolbox to measure diversification. Specifically, this framework provides recent diversification measures from the recent literature. These diversification measures are based on the works of Rudin and Morgan (2006) <doi:10.3905/jpm.2006.611807>, Choueifaty and Coignard (2008) <doi:10.3905/JPM.2008.35.1.40>, Vermorken et al. (2012) <doi:10.3905/jpm.2012.39.1.067>, Flores et al. (2017) <doi:10.3905/jpm.2017.43.4.112>, Calvet et al. (2007) <doi:10.1086/524204>, and Candelon, Fuerst and Hasse (2020).
