The accuracy of the vast amount of genotypic information generated by high-throughput genotyping technologies is crucial in haplotype analyses and linkage-disequilibrium mapping for complex diseases. To date, most automated programs lack quality measures for the allele calls; therefore, human interventions, which are both labor intensive and error prone,(More)
The Chandra X-Ray Observatory, launched by the space shuttle Columbia in July 1999, has taken its place with the Hubble Space Telescope, the Compton Gamma Ray Observatory and the Spitzer Infrared Space Telescope in NASA's fleet of state of the art space-based Great Observatories. As the world's premier X-ray observatory, Chandra gives astronomers a powerful(More)
In recent years, there has been an avalanche of new data in observational high-energy astrophysics. Recently launched or soon-to-be launched space-based telescopes that are designed to detect and map ultraviolet , X-ray, and γ-ray electromagnetic emission are opening a whole new window to study the cosmos. Because the production of high-energy(More)
Marginal Data Augmentation and Parameter-Expanded Data Augmentation are related methods for improving the the convergence properties of the two-step Gibbs sampler know as the Data Augmentation sampler. These methods expand the parameter space with a so-callled working parameter that is unidentifiable given the observed data but is identifiable given the(More)
