Dissertation
Analysis of finite population surveys : sample size and testing considerations

Creator:

McDonald, Trent, 1965-

Abstract:

This dissertation concerns two topics in the analysis of finite population surveys: setting sample size and hypothesis testing. The first concerns the a priori determination of the sample size needed to obtain species members. The second concerns testing distributional hypotheses when two equal-size populations are sampled. Setting sample size to...

Tools for environmental statistics : creative visualization and estimating variance from complex surveys

Creator:

Courbois, Jean-Yves Pip

Abstract:

Environmental monitoring poses two challenges to statistical analysis: complex data and complex survey designs. Monitoring for system health involves measuring physical, chemical, and biological properties that have complex relations. Exploring these relations is an integral part of understanding how systems are changing under stress. How does one explore high dimensional...

Dissertation
Statistical aspects of two measurement problems : defining taxonomic richness and testing with unanchored responses

Creator:

Ritter, Kerry

Abstract:

Statisticians often focus on sampling or experimental design and data analysis while paying less attention to how the response is measured. However, the ideas of statistics may be applied to measurement problems with fruitful results. By examining the errors of measured responses, we may gain insight into the limitations of...
