Massively parallel analysis of the functional effects of mutations
Massively parallel assays can dramatically advance our understanding of biological processes. Coupling them with modern mutagenesis techniques allows for fine mapping of the link between genotype and phenotype. In this dissertation, I first discuss the current state of the field of using massively …

Performance of Number of Factors Procedures in Higher Order Analysis: A Comparative Study
<p>Exploratory Factor Analysis (EFA) is one of the primary statistical tools available for the verification of the structure of a psychological measure. In the case of a nested test the structure of the higher levels is verified by performing EFA on the factor scores of the lower levels, a process …

A Comparison of Teleneuropsychological and Traditional Neuropsychological Battery Factor Structures
… Factor Analyses (EFA) using Principal Component Analysis (PCA) method were conducted on the T-scores and scaled scores of each subtest to compare the internal factor structures of the two neuropsychological batteries. For hypothesis one, it was hypothesized an EFA using PCA method of the subtests …
