`ASRV.Gamma_quadrature` — The quadrature-discretized Gamma rate heterogeneity model

Usage

ASRV.Gamma_quadrature(submodel: DiscreteDist<CTMC<a>>,
n: Int, alpha: Double) → DiscreteDist<CTMC<a>>

Arguments

A default beginning with ~ specifies a prior distribution.

submodel:: The model being scaled
n:: The number of Gamma quadrature nodes; Default: 4
alpha:: The shape parameter for the Gamma distribution; Default: ~LogLaplace(6,2)

Description

This model uses Gaussian quadrature to approximate Gamma-distributed rates across sites.
