treeducken: An R package for simulating cophylogenetic systems
Published 2021-08-01“…Simulation is necessary for testing cophylogenetic methods, but few simulators exist that are capable of generating data under explicit and biologically meaningful models. We present an R package, treeducken, for simulating host–symbiont evolution and gene‐tree–species‐tree evolution. treeducken provides a straightforward and reproducible interface for simulating cophylogenetic data. …”

The reproduction number $R_t$ in structured and nonstructured populations
Published 2009-02-01“…Other methods to estimate $R_t$ arebased on explicit models such as the SIR model; therefore, onemight expect the WT method to be more robust to departures from SIR-type behavior.This paper uses simulated data to compare the quality of daily $R_t$ estimates based on a SIR model tothose using the WT method for both structured(classical SIR assumptions are violated) and nonstructured (classical SIR assumptions hold) populations.By using detailed simulations that record the infection day of each new infectionand the donor-recipient identities, the true $R_t$ and the generation interval pdf isknown with negligible error. …”
