MORA is a real-time regression analysis method that incorporates both dynamics and inter-data batch correlation.

An incremental data analytic based on quadratic inference function (QIF) to analyze streaming correlated datasets, with a screening procedure on occurrences of abnormal data batches.

Detection and prediction of ovulation by incorporating biorhythm information in processing high frequency basal body temperature measurements via hidden Markov model (HMM).

Mathematical Statistics I (STAT4100)

University of Iowa

Aug 2020 – Dec 2020 Iowa City, Iowa
This is a course in mathematical statistics intended for upper-level undergraduate students in the mathematical sciences as well as for graduate students in all disciplines. The goal is to provide a solid foundation in th theory of random variables and probability distributions.

  • Probability and distributions (sets, random variables, expectation, important inequalities)
  • Multivariate distributions (joint/marginal distributions, transformation, independence)
  • Some special distributions (Binomial, Negative Binomial, Geometric, Poisson, Normal)
