Pnd: Probability density of node depths.

In sophia-lambert/UDivEvo: A package for Unknown Diversity Diversification Analysis in Evolution

Probability density of node depths.

Description

Calculating the probability density of node depths of a phylogenetic tree.

Usage

Pnd(t, r, epsi, y)

Arguments

t	Numeric vector. A vector specifying the node depths of a phylogeny in millions of years.
r	Numeric. The net diversification rate: λ - μ. The units are in events/lineages/millions years.
epsi	Numeric. The turnover rate: μ / λ. The units are in events/lineages/millions years.
y	Numeric. The sampling probability also called sampling fraction: k / N.

Value

The probability density of node depths equivalent to f\_y(t) in Lambert 2018 and to λ * p1 in Stadler 2010 and Lambert et al. 2022.
