This thesis may be broadly divided into two parts.The first part critically discusses various aspects of path analysis as a statistical tool for abstract analysis. The second part investigates the changing pattern of nuptiality in Bangladesh by districts using 1981 census data. Path analysis has been applied to find and analyze the nature and extent the of causal relationship between the dependent variable, nuptiality and its determinants. It is observed that education, urbanization,female employment and economic development are all strongly positivelyrelatedto nuptiality. That is, formal and effective education policy combined with proper urbanization and development policies may increase the female employment rate which in turn will raise age at marriage. Further, effects of various indices through childlessness is reasonably high. This indicates that appropriate population distribution policies and introduction of insurance schemes for childless couples and couples with fewer children may indirectly put positive effect on nuptiality.Ball State UniversityMuncie, IN 47306

In Voronoi-based nearest neighbor search, the Voronoi cell of every point p in a database can be used to check whether p is the closest to some query point q. We extend the notion of Voronoi cells to support uncertain objects, whose attribute values are inexact. Particularly, we propose the Possible Voronoi cell (or PV-cell). A PV-cell of a multi-dimensional uncertain object o is a region R, such that for any point p ∈ R, o may be the nearest neighbor of p. If the PV-cells of all objects in a database S are known, they can be used to identify objects that have a chance to be the nearest neighbor of q. However, there is no efficient algorithm for computing an exact PV-cell. We hence study how to derive an axis-parallel hyper-rectangle (called the Uncertain Bounding Rectangle, or UBR) that tightly contains a PV-cell. We further develop the PV-index, a structure that stores UBRs, to evaluate probabilistic nearest neighbor queries over uncertain data. An advantage of the PV-index is that upon updates on S, it can be incrementally updated. Extensive experiments on both synthetic and real datasets are carried out to validate the performance of the PV-index. / published_or_final_version / Computer Science / Master / Master of Philosophy
