Statistical computing and computational statistics
Signal extractions and uncertainty assessments
- Statistical Theory and Principles toward the foundation of Data Science;
- Multi-resolution Inferences, such as accumulating statistical evidence for individualized treatments (high resolution prediction) and dealing with partial prior knowledge (low resolution information);
- Multi-phase Inferences, such as handling uncongeniality between data pre-processors (e.g., imputers) and data analysts and preserving information in a distributed pre-processing system;
- Multi-source Inferences, such as comparing large observational datasets with small probabilistic samples and designing methods to gain combined information guided by bias-variance trade-off;
- Philosophical and Foundational Issues in Statistics, such as connecting and the interplay between Bayesian, Fiducial, and frequentist (BFF) perspectives, and their extensions, including belief function;
- Statistical Computing and Computational Statistics, such as Markov chain Monte Carlo, EM-type algorithms and their self-consistent generalizations, and user-friendly combining rules for multiple-imputation inference;
- Signal extractions and Uncertainty Assessments in natural, social, and medical sciences, such as in astronomy/astrophysics and in psychology/psychiatry;
- Elegant Mathematical Statistics, especially distribution theory and stochastic algebra
