Thesis (Ph.D.)--The Pennsylvania State University, 2003.

In this thesis, an ancestral mixture model for clustering discrete multivariate data is proposed. This model has a natural relationship to the coalescent process of population genetics. The sieve parameter in the model plays the role of time in the evolutionary tree of the sequences. By sliding the sieve parameter, one can create a hierarchical tree that estimates the population structure at each fixed backward point in time.Subjects--Topical Terms:

520 $a In this thesis, an ancestral mixture model for clustering discrete multivariate data is proposed. This model has a natural relationship to the coalescent process of population genetics. The sieve parameter in the model plays the role of time in the evolutionary tree of the sequences. By sliding the sieve parameter, one can create a hierarchical tree that estimates the population structure at each fixed backward point in time.
520 $a A preliminary computer study of clustering the mtDNA sequences of Griffiths et al. (1994) indicates our approach performs well. The author also further develop some theoretical and computational properties of the ancestral mixture model. A quadratic distance based model selection for goodness of fit is proposed. In addition, some potential applications including haplotype reconstruction, estimating the human nucleotide diversity from shotgun sequencing data, and comparing case and control groups in disease studies are discussed. It is believed the ancestral mixture model could be a simple powerful tool in these studies.
