Bayesian Model Testing Of Models For Ellipsoidal Variation On Stars Due To Hot Jupiters, Anthony Gai Jan 2016

Bayesian Model Testing Of Models For Ellipsoidal Variation On Stars Due To Hot Jupiters, Anthony Gai

Legacy Theses & Dissertations (2009 - 2024)

A massive planet closely orbiting its host star creates tidal forces that distort the typically spherical stellar surface. These distortions, known as ellipsoidal variations, result in variations in the photometric flux emitted by the star, which can be detected by the Kepler Space Telescope. Currently, there exist several models describing such variations and their effect on the photometric fux [1] [2] [3] [4]. By using Bayesian model testing in conjunction with the Bayesian-based exoplanet characterization software package EXONEST [4] [5] [6], the most probable representation for ellipsoidal variations was determined for synthetic data and two systems with confirmed hot Jupiter …


Topic Modeling For E-Petition Analysis : Interpreting Petitioners' Policy Priorities, Loni Hagen Jan 2016

Topic Modeling For E-Petition Analysis : Interpreting Petitioners' Policy Priorities, Loni Hagen

Legacy Theses & Dissertations (2009 - 2024)

The Obama Administration launched an e-petitioning site called “We the People” (WtP) in 2011 to encourage the submission of citizens’ policy suggestions. Since 2011, thousands of petitions have been submitted to this site. Analysis of the contents of petition texts using topic modeling may enable policy makers and government leaders to identify latent topics of public interest that are not otherwise apparent.


The Decision-Making Processes Of Nontraditional Or For Sale By Owner (Fsbo) Home Sellers Engaged In The Listing And Sale Of Their Homes, Valentin Demarco Jr. Jan 2016

The Decision-Making Processes Of Nontraditional Or For Sale By Owner (Fsbo) Home Sellers Engaged In The Listing And Sale Of Their Homes, Valentin Demarco Jr.

Legacy Theses & Dissertations (2009 - 2024)

In spite of promises that the Internet would allow people to buy and sell their homes without intermediaries, real-estate agents still control approximately 90% of the transactions made in the 2.5-trillion-dollar residential real-estate industry. Existing literature has yet to provide conclusive arguments as to why the expected disintermediation has not occurred. Tentative arguments include claims that policy is biased in favor of agents, or that agents have a broader social network than their customers which helps them sell faster and for a better price. Most studies make the assumption that agents matter. They analyze the real-estate market from the perspective …
