...Harvard researchers applied an innovative Bayesian modeling method to gene sequences from both untreated HIV patients and those treated with drugs. Having ran a comprehensive computer search for over a month, the researchers looked for patterns of mutation that were more prevalent among the treated patients—the more common the mutation, the greater the probability of it being responsible for the drug resistance, according to Jun Liu, a professor of statistics at the Harvard School of Public Health and one of the authors of the paper...
...group of researchers at Harvard and Massachusetts General Hospital have published findings on a new, more accurate method to predict stroke risk through a statistical model that screens for thousands of potentially stroke-causing genes. The model—called a Bayesian network—differs from existing methods that examine only the effect of a single factor, instead allowing researchers to study the interaction of multiple genes. The study, released last month, found the formula could predict a person’s risk for the most common stroke in the U.S. with 86 percent accuracy—which...
...award committee cited Rubin's contributions to "statistics and methodology, particularly in causal inference; design and analysis of experimental and sample surveys treatment of missing data; Bayesian data analysis, methods of imputations for non-response; equating tests; and a variety of applications...
Rubin said Bayesian data analysis refers to methods that build probability distributions for unknown quantities. Imputation is filling in for missing data, as when people in surveys refuse to answer some questions. Equating refers to the process used by testing organizations such as Educational Testing Services to ensure different forms of a test are basically equivalent...
