lambda_N {apTreeshape}R Documentation

Computation of lambda_epsilon

Description

Computes the parameter lambda_epsilon for n in 1:N

Usage

lambda_N(epsilon, beta, N, upper = 10000)

Arguments

epsilon

Minimum size of unsampled splits (see appendix 1)

beta

The beta parameter quantifying the balance of the tree

N

Tip number

upper

Upper bound from the integral (see lambda_n expression, default to 10000)

Details

λ_ε = 2 \int_(ε,∞) exp(-(β+n+1)x)(1-exp(-x))^β dx
