Description Usage Arguments Details Author(s) References

Computes the parameter lambda_epsilon for n in 1:N

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

`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)

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