Mathematica’s mission is to improve public well-being by bringing the highest standards of quality, objectivity, and excellence to bear on the provision of information collection and analysis to our clients. As such, our research teams are carefully selected to include experts who are uniquely qualified to carry out each step of a research project from start to finish. Mathematica’s statisticians are crucial members of these teams, bringing expertise to all aspects of design and analytic techniques. Their established roles in complex sample designs, experimental and observational study designs, data collection and processing, and statistical inference have been augmented by expanded, modern capabilities in data analytics, advanced statistical computing, Bayesian modeling, data mining, and machine learning.
