simapp: Generating Random DNA Samples Using Approximation Method

Description

This function generates random DNA samples using an approximation method

Usage

simapp(theta, seqLength, merge1)

Arguments

theta

a vector of variables containing the following parameters in this order--1. the first three parameters from $\pi_X$ vector, 2. the first three parameters from $\pi_Y$ vector, 3. the first three parameters from $f_0$ vector, 4. the six off-diagonal free parameters in the S matrix, 5. a scalar $\rho$, 6. a vector of lengths containing K-2 values

seqLength

the length of sequences we need to generate

merge1

(K-1) x 2 matrix describing the tree topology

Value

Details

This function generates a $4^K$ DNA array using an approximation method. It depends on a set of variables theta, the sequence length and a merge matrix describing the tree topology.
