Summary

AnnealedSMC is a recently proposed algorithm (annealed sequential Monte Carlo) with the adaptive determination of annealing parameters based on the relative conditional effective sample size for Bayesian phylogenetics. This algorithm provides an unbiased estimator for the probability of the data. This unbiasedness property can be used for the purpose of testing the correctness of posterior simulation software. Unlike the previous SMC methods in phylogenetics, the annealed SMC has the same state space for all the intermediate distributions, which allows standard Markov chain Monte Carlo (MCMC) tree moves to be utilized as the basis for SMC proposal distributions.

Installation

There are several options available to install the package:

Integrate to a gradle script

Simply add the following lines (replacing 1.0.0 by the current version (see git tags)):

repositories {
 mavenCentral()
 jcenter()
 maven {
    url "http://people.stat.sfu.ca/~lwa68/maven/"
  }
}

dependencies {
  compile group: 'ca.sfu.stat', name: 'annealedSMC', version: '1.0.0'
}

Compile using the provided gradle script

  • Check out the source git clone git@github.com:liangliangwangsfu/annealedSMC.git
  • Compile using ./gradlew installDist
  • Add the jars in build/install/annealedSMC/lib/ into your classpath

Use in eclipse

  • Check out the source git clone git@github.com:liangliangwangsfu/annealedSMC.git
  • Type gradle eclipse from the root of the repository
  • From eclipse:
    • Import in File menu
    • Import existing projects into workspace
    • Select the root
    • Deselect Copy projects into workspace to avoid having duplicates
