Population stratification referes to clustering people of a population based on their original subpopulations. In this talk, the statistical model underlying the population structure will be presented. Based on the model, the theoretical aspects of population stratification will be investigated. In particular, sample size complexity for inferring the subpopulation will be discussed. Moving to association mapping, we develop a framework which jointly infers  the disease causal factors and the hidden population structures. In this regard, a Markov Chain-Monte Carlo (MCMC) procedure has been employed to assess the posterior probability distribution of the model parameters.
