Essays on average treatment effects
… consists of three essays on estimating average treatment effects (ATE) under counterfactual framework. In Chapter 1, I compare the performances of single-step and two-step estimators for estimating the ATE in a linear model when treatment assignment depends on unobservables. Recent advances in …

Causal Inference Beyond Estimating Average Treatment Effects
… control groups that is often called the average treatment effect (ATE), and rely on identifying assumptions to allow causal interpretation. However, more specific treatment effects beyond the ATE can be estimated under the same assumptions. For example, instead of estimating the mean of potential …

Topics In Statistical Inference For Treatment Effects
… discussing different approaches for estimating treatment effects, either in observational study or randomized trial. The first paper presents an approach to sensitivity analysis for the instrumental variable(IV) method, which examines the sensitivity of inferences to violations of IV validity. …

Statistical methods to study heterogeneity of treatment effects
… studies are designed to estimate the average treatment effect (ATE) of an intervention. Individuals may derive quantitatively, or even qualitatively, different effects from the ATE, which is called the heterogeneity of treatment effect. It is important to detect the existence of heterogeneity …

ESSAYS ON HETEROGENEOUS TREATMENT EFFECTS IN THE LABOR MARKET
… The first two chapters mainly focus on the effects of job displacement on earnings. The first chapter analyzes how the effects of job displacement on earnings vary among natives and immigrants in the United States, while the second chapter studies the distributional effects of job …

Treatment Effects of Incisor Positioning on Anterior Tooth Display
… adolescent (n = 38) orthodontic patients. The effects of anterior-posterior, vertical, and angular changes of the maxillary central incisor position during orthodontic treatment were evaluated relative to changes in the amount of ATD measured from pretreatment (TI) and posttreatment (T2) …

Moderating Variables in the Treatment Effects of Second Step
… occurrence of youth violence and its negative effects. One approach to preventing youth violence has been to deliver social emotional learning programs to children and adolescents in school settings. Social emotional learning programs are designed to provide children with skills and strategies …

Post Harvest Treatment Effects on Crown-Cut Broccoli Shelf Life
The effects of packaging treatments, post harvest cooling delay and storage duration on color, texture, ascorbic acid content, weight loss and glucosinolate retention in crown-cut heads of broccoli were studied. Oxygen and CO2 levels inside shrink wrap packages were also monitored. Shrink wrap …

Examining Treatment Effects for Single-Case ABAB Designs through Sensitivity Analyses
… models (HLM) allow for statistical analyses of treatment effects (Nagler, Rindskopf, & Shadish, 2008), thus making it possible to compare and contrast results from HLM and visual analyses to ascertain if the different methods yield consistent conclusions. This work performed a series of …

The external validity of treatment effects: an investigation of educational production
… review of the literature on the extrapolation of treatment effects ('external validity'). Building on the insights of Cook and Campbell (1979) and a result by Hotz, Imbens, and Mortimer (2005), I then argue that the fundamental challenge to external validity may be interactive relationships …

Nicotine fading, behavioral contracting, and extended treatment: effects on smoking cessation
Two approaches to smoking cessation were evaluated. One approach, the standard condition, utilized a nicotine fading procedure, group support, and an attendance contingent monetary contract. The other approach, the maintenance condition, utilized nicotine fading, group support, and a …

Characterizing heterogeneous treatment effects of couple relationship education : a machine learning approach
… a large body of research indicates that treatment effects of CRE exhibit a great deal of variability depending on the pretreatment conditions and the characteristics of the program attendees (Wadsworth & Markman, 2012). Given that significant federal expenditures have been invested to …

Repeated Zolpidem Treatment Effects on Sedative Tolerance, Withdrawal, mRNA Levels, and Protein Expression
… of symptoms that occur due to abrupt end of drug treatment. Zolpidem is a short-acting, non-BZ GABAAR PAM whose potential for tolerance and withdrawal is unclear. Zolpidem demonstrates sedative efficacy similar to BZs and has become a main treatment of insomnia in lieu of BZs. Zolpidem replaced …
