Statistical Analysis in Two Stage Randomization Designs in Clinical Trials
… We use the concepts of counting process and risk set as described by Fleming and Harrington (1991) to find weighted estimating equations whose solution gives an estimator for the cumulative hazard function which, in turn, is used to derive an estimator for the overall survival distribution …

Differential Development of Delinquent Behavior In A Matched Sample of Gang- and Nongang- Affiliated Youth
… predicting this crime. Differences in background risk factors between gang- and nongang- affiliated youth confound the relationship between gang-affiliation and delinquency. The aim of this study was to examine differential development and differential onset of antisocial behavior between a …

Do Women Ask? Gender Differences in Applying for Internal Job Openings
… have the advantage of being able to observe the risk set of potential applications in this setting. Our findings show few differences in application rates by gender, even when considering variation in hierarchical distance of the opportunity or the level from which the candidate is applying. …

Beyond Parameter Estimation: Analysis of the Case-Cohort Design in Cox Models
… Cases are over-represented in the dataset, and hence estimation of coefficients in this design requires weighting of observations. This results in a pseudopartial likelihood, and standard post-estimation methods may not be readily transferable to the case-cohort design. This thesis …

Exploring Ethnocultural Differences in Distress of Newly Arrived Refugees During Early Resettlement: A Mixed Methods Dissertation
… Republic of Congo during the first year of resettlement in Denver, Colorado. Utilizing RHS-15 quantitative outcomes and demographic data collected approximately every 3 months for 1 year, three approaches to propensity score analysis were performed with risk set matching on balancing …

Analyzing Electricity Use of Low Income Weatherization Program Participants Using Propensity Score Analysis and a Hierarchical Linear Growth Model
… Denver, Colorado. Propensity score analysis with risk set matching was performed at each month under analysis applying nearest neighbor and nearest neighbor with caliper approaches by balancing covariates across the treatment and control groups. Following the completion of propensity score …

Adoption and maintenance of health behaviors among middle-aged and older adults: the role of chronic disease diagnosis and depression
… Kaplan-Meier estimator and the marginal risk set model were performed to assess the impact of a chronic disease diagnosis, depression, and their interaction on the likelihood of relapse after a health behavior change had been initiated. Middle-aged and older adults tended to reduce …

A DATA-DRIVEN PRIORITIZATION ALGORITHM FOR MEDICATION REVIEW IN OLDER ADULTS: FROM REAL-WORLD EVIDENCE TO CLINICAL PRACTICE
… pharmacological regimens not only increase the risk of adverse drug reactions and hospitalizations but also contribute to excessive healthcare costs and a decline in patient quality of life. Given their unique clinical complexity and physiological vulnerability, older adults are particularly …
