A Monte Carlo Analysis Of Ordinary Least Squares Versus Equal Weights, James Brewer Ayres
A Monte Carlo Analysis Of Ordinary Least Squares Versus Equal Weights, James Brewer Ayres
Masters Theses & Specialist Projects
Equal weights are an alternative weighting procedure to the optimal weights offered by ordinary least squares regression analysis. Also called units weights, equal weights are formed by standardizing scores on the predictor variables and averaging these standardized scores to create a composite score. Research is limited regarding the conditions under which equal weights result in cross-validated 𝑅𝑅2 values that meet or exceed optimal weights. In this study, I explored the effect of various predictor-criterion correlations, predictor intercorrelations, and sample sizes to determine the relative performance of equal and optimal weighting schemes upon cross-validation. Results indicated that optimally weighted predictors explained …
The Language Of Breathing, Brian Wallace Baker
The Language Of Breathing, Brian Wallace Baker
Masters Theses & Specialist Projects
The Language of Breathing is an eclectic collection of 18 creative nonfiction essays that capture moments from the author’s life and attempt to give them meaning through narrative and metaphor. They deal with relationships, nature, faith, and often rely on background research to pair art, mythology, current events, and science with personal experience.
Hydrogeochemical Characterization And Speleogenesis Of Sistema Huautla In Oaxaca, Mexico, Fernando Hernandez
Hydrogeochemical Characterization And Speleogenesis Of Sistema Huautla In Oaxaca, Mexico, Fernando Hernandez
Masters Theses & Specialist Projects
Sierra Mazateca, Mexico is home to Sistema Huautla, the deepest cave in the Western hemisphere with 1,560 meters of depth and 90 kilometers of passage, including 26 entrances distributed in a high-relief, karstified terrain, within the Sistema Huautla Karst Groundwater Basin. Exploration of the cave has generated research questions about its evolution and geomorphology given the different vadose and phreatic zones impacted by tectonic and incision processes. Dye traces during this study of Cueva de La Peña Colorada confirmed it is a fossil resurgence of the cave system. An additional cave, Cueva Elysium, was connected hydrologically in 2019, expanding the …
A Monte Carlo Analysis Of Standard Error-Based Methods For Computing Confidence Intervals, Elayna Wichert
A Monte Carlo Analysis Of Standard Error-Based Methods For Computing Confidence Intervals, Elayna Wichert
Masters Theses & Specialist Projects
The objective of this study is to empirically test existing techniques to calculate the likely range of values for a Classical Test Theory true score given an observed score. The traditional method for forming these confidence intervals has used the standard error of measurement (SEM) as the basis for this confidence interval. An alternate equation, the standard error of estimate (SEE), has been recommended in place of the SEM for this purpose, yet it remains overlooked in the field of psychometrics. It is important that the correct equation be used in various applications in personnel psychology. Monte Carlo analyses were …
Interdependence Across Foreign Exchange Rate Markets- A Mixed Copula Approach, Richard Adjei-Boateng
Interdependence Across Foreign Exchange Rate Markets- A Mixed Copula Approach, Richard Adjei-Boateng
Masters Theses & Specialist Projects
The purpose of this thesis is to study the dependence structure of exchange rate pairs using a mixture of copula as opposed to a single copula approach. Mixed copula models have the ability to generate dependence structures that do not belong to existing copula families. The flexibility in choosing component copulas in this mixture model aids the construction of a system that is simultaneously parsimonious and flexible enough to generate most dependence patterns in exchange rate data. Furthermore, the method of mixture copulas facilitates the separation of both the structure and degree of dependence, concepts that are respectively embodied in …
The Enhancement Of Climate Change Science Communication And Understanding Through Glacier Tourism, Natalie Jean Kincheloe
The Enhancement Of Climate Change Science Communication And Understanding Through Glacier Tourism, Natalie Jean Kincheloe
Masters Theses & Specialist Projects
The natural environment provides the opportunity for educators to teach the general public about scientific topics that are misunderstood. Arctic tourism has increased as accessibility to these regions has improved. Informal learning is a valuable yet extremely understudied phenomenon within the tourism industry. Iceland is a country that lies in the North Atlantic and has experienced a significant increase in foreign visitors over the past decade. Of the natural features in Iceland, glaciers have become a top attraction for visitors. Since thousands of visitors participate in guided glacier tours annually in Iceland, an opportunity to couple glacier tourism with informal …
