Bayesian Analysis for Social Science Research

Carolina Luque, Juan Sosa

In this manuscript, we discuss the substantial importance of Bayesian reasoning in Social Science research. Particularly, we focus on foundational elements to fit models under the…

Conditional Relative Risk: An association measure for longitudinal data analysis

Lina Buitrago, Juan Sosa, Oscar Melo

In this paper, we propose a novel association measure for longitudinal studies based on the traditional definition of relative risk. In a Markovian fashion, such a proposal takes i…

A robust Bayesian latent position approach for community detection in networks with continuous attributes

Zhumengmeng Jin, Juan Sosa, Shangchen Song +1

The increasing prevalence of multiplex networks has spurred a critical need to take into account potential dependencies across different layers, especially when the goal is communi…

Operationalizing Legislative Bodies: A Methodological and Empirical Perspective

Carolina Luque, Juan Sosa

This manuscript extensively reviews applications, extensions, and models derived from the Bayesian ideal point estimator. We primarily focus our attention on studies conducted in t…

Bayesian modeling of the political preferences of the Colombian Senate 2006-2010: electoral behavior and parapolitics

Juan Valero, Juan Sosa, Carolina Luque

In this paper, a Bayesian spatial voting model is applied for the first time to characterize the legislative behavior of the Senate of the Republic of Colombia for the period 2006-…

Small area estimation using multiple imputation in three-parameter logistic models

Cristian Tellez-Piñerez, Leonardo Trujillo, Andrés Gutiérrez-Rojas +1

We propose a novel methodology relating item response theory methods with small area estimation strategies in the presence of missing data. Specifically, we propose an unbiased est…

Some Case Studies Using Bayesian Statistical Models

Juan Sosa, Lina Buitrago

We provide four case studies that use Bayesian machinery to making inductive reasoning. Our main motivation relies in offering several instances where the Bayesian approach to data…

A Gentle Introduction to Bayesian Hierarchical Linear Regression Models

Juan Sosa, Jeimy Aristizabal

Considering the flexibility and applicability of Bayesian modeling, in this work we revise the main characteristics of two hierarchical models in a regression setting. We study the…

Time-Varying Coefficient Model Estimation Through Radial Basis Functions

Juan Sosa, Lina Buitrago

In this paper we estimate the dynamic parameters of a time-varying coefficient model through radial kernel functions in the context of a longitudinal study. Our proposal is based o…

A Latent Space Model for Multilayer Network Data

Juan Sosa, Brenda Betancourt

In this work, we propose a Bayesian statistical model to simultaneously characterize two or more social networks defined over a common set of actors. The key feature of the model i…

A Review of Latent Space Models for Social Networks

Juan Sosa, Lina Buitrago

In this paper, we provide a review on both fundamentals of social networks and latent space modeling. The former discusses important topics related to network description, includin…

A Prior for Record Linkage Based on Allelic Partitions

Brenda Betancourt, Juan Sosa, Abel Rodríguez

In database management, record linkage aims to identify multiple records that correspond to the same individual. This task can be treated as a clustering problem, in which a latent…

A Bayesian Approach for De-duplication in the Presence of Relational Data

Juan Sosa, Abel Rodriguez

In this paper, we study the impact of combining profile and network data in a de-duplication setting. We also assess the influence of a range of prior distributions on the linkage…

A Record Linkage Model Incorporating Relational Data

Juan Sosa, Abel Rodriguez

In this paper we introduce a novel Bayesian approach for linking multiple social networks in order to discover the same real world person having different accounts across networks.…

A Latent Space Model for Cognitive Social Structures Data

Juan Sosa, Abel Rodriguez

This paper introduces a novel approach for modeling a set of directed, binary networks in the context of cognitive social structures (CSSs) data. We adopt a relativist approach in…
