We develop a method for improved estimation of a participant’s inclusion probability based on their network size (degree) as well as other information.

Claiming causal inferences in network settings necessitates careful consideration of the often complex dependency between outcomes for …

We show that smartphone based Exposure Notification systems can significantly improve the accuracy of short-term forecasting of COVID-19 caseloads.

We argue that a new class of exponential-family models for networks is more appriopriate when some of the covariates are stochastic.

Probabilistic performance-based earthquake engineering frameworks depend on the choice of an optimal ground motion intensity measure. We evaluate this choice based on two widely known evaluation metrics: efficiency and sufficiency.

The promise of upward mobility—the notion that everyone has the chance to get ahead—is one of this country’s most cherished …

In social science research, differences among groups or changes over time are a common focus of study. While means and variances are …

The most effective way to learn statistics is by actively engaging in doing the statistical analysis. This idea drives this casebook. …

Most inference using social network models assumes that the presence or absence of all relations is known. This is rarely the case. …

In this paper, we illustrate that combining ecological data with subsample data in situations in which a linear model is appropriate …

In many situations information from a sample of individuals can be supplemented by population level information on the relationship …

Network models are widely used to represent relations among interacting units or actors. Network data often exhibit transitivity, …

Network data arise in a wide variety of applications. Although descriptive statistics for networks abound in the literature, the …

We present a systematic examination of real network datasets using maximum likelihood estimation for exponential random graph models as …

The most promising class of statistical models for expressing structural properties of social networks is the class of Exponential …

Recent advances in latent space and related random effects models hold much promise for representing network data. The inherent …

This paper presents recent advances in the statistical modeling of random graphs that have an impact on the empirical study of social …

Regression coefficients specify the partial effect of a regressor on the dependent variable. Sometimes the bivariate, or limited …
