An Introductory Overview of Statistical Methods for Discrete Time Series Xiao-li Meng (Harvard University) A number of statistical problems encounted in astrophysics are concerned with discrete time series, such as photon counts with variation in source intensity over time. This talk provides an introductory overview of the current state-of-the-art methods in statistics, including Bayesian methods aided by Markov chain Monte Carlo, for modeling and analyzing such data. If time permits, I will also briefly discuss the successful applications of such methods in other fields, such as economics.
