Multiple testing in candidate gene situations: a comparison of classical, discrete, and resampling-based procedures.

abstract：:The Dirichlet Process (DP) mixture model has become a popular choice for model-based clustering, largely because it allows the number of clusters to be inferred. The sequential updating and greedy search (SUGS) algorithm (Wang & Dunson, 2011) was proposed as a fast method for performing approximate Bayesian inference ...
