tonedata

<p>The tone perception data stem
  from an experiment of Cohen (1980) and have been analyzed in de Veaux
  (1989) and Viele and Tong (2002).  The dataset and this documentation file
  were copied from the fpc package by Christian Hennig.
  A pure fundamental tone was played to a
  trained musician. Electronically generated overtones were added, determined 
  by a stretching ratio of <code>stretchratio</code>. <code>stretchratio=2.0</code>
  corresponds to the harmonic pattern
  usually heard in traditional definite pitched instruments. The musician was
  asked to tune an adjustable tone to the octave above the fundamental tone.
  <code>tuned</code> gives the ratio of the adjusted tone to the fundamental,
  i.e. <code>tuned=2.0</code> would be the correct tuning for all
  <code>stretchratio</code>-values.
  The data analyzed here belong to 150 trials 
  with the same musician. In the original study, there were four further
  musicians.</p>

datasets

Analyzes finite mixture models for various parametric and semiparametric settings.  This includes mixtures of parametric distributions (normal, multivariate normal, multinomial, gamma), various Reliability Mixture Models (RMMs), mixtures-of-regressions settings (linear regression, logistic regression, Poisson regression, linear regression with changepoints, predictor-dependent mixing proportions, random effects regressions, hierarchical mixtures-of-experts), and tools for selecting the number of components (bootstrapping the likelihood ratio test statistic, mixturegrams, and model selection criteria).  Bayesian estimation of mixtures-of-linear-regressions models is available as well as a novel data depth method for obtaining credible bands.  This package is based upon work supported by the National Science Foundation under Grant No. SES-0518772.
