An island of trust
This contribution aims to better understand the level of and reasons for the trust U.S. television viewers place in the Public Broadcasting Service (PBS) amidst what is often perceived as a general decline in trust in U.S. media and public institutions. Based on a nationwide survey of 1533 self-declared PBS viewers and rooted in theories of the conceptualization of organizational trust, our findings suggest that PBS viewers trust PBS along three …
Interpretation and identification of within-unit and cross-sectional variation in panel data models
While fixed effects (FE) models are often employed to address potential omitted variables, we argue that these models' real utility is in isolating a particular dimension of variance from panel data for analysis. In addition, we show through novel mathematical decomposition and simulation that only one-way FE models cleanly capture either the over-time or cross-sectional dimensions in panel data, while the two-way FE model unhelpfully combines wi…
Beyond the Hazard Ratio
The Cox proportional hazards model is a commonly used method for duration analysis in political science. Typical quantities of interest used to communicate results come from the hazard function (for example, hazard ratios or percentage changes in the hazard rate). These quantities are substantively vague, difficult for many audiences to understand and incongruent with researchers’ substantive focus on duration. We propose methods for computing ex…
Simulating Duration Data for the Cox Model
The Cox proportional hazards model is a popular method for duration analysis that is frequently the subject of simulation studies. However, no standard method exists for simulating durations directly from its data generating process because it does not assume a distributional form for the baseline hazard function. Instead, simulation studies typically rely on parametric survival distributions, which contradicts the primary motivation for employin…
Issue Scales, Information Cues, and the Proximity and Directional Models of Voter Choice
One of the most important questions in the study of democratic politics centers on how citizens consider issues and candidate positions when choosing whom to support in an election. The proximity and directional theories make fundamentally different predictions about voter behavior and imply different optimal strategies for candidates, but a longstanding literature to empirically adjudicate between the theories has yielded mixed results. We use a…
Multiple Imputation for Continuous and Categorical Data
We consider the relative performance of two common approaches to multiple imputation (MI): joint multivariate normal (MVN) MI, in which the data are modeled as a sample from a joint MVN distribution; and conditional MI, in which each variable is modeled conditionally on all the others. In order to use the multivariate normal distribution, implementations of joint MVN MI typically assume that categories of discrete variables are probabilistically …
Epidemiology of Drug Use among Biracial/Ethnic Youth and Young Adults
This study estimates the prevalence of cigarette, alcohol, and marijuana use in a nationally representative sample of monoracial/ethnic and biracial/ethnic youth and young adults. The authors consider 16 racial/ethnic categories and used four waves of data from the National Longitudinal Study of Adolescent Health. The analysis sample consists of 20,745 individuals in Wave 1. The primary statistical methodology used in the present study is logisti…
