Estrategia para la selección de modelos gráficos en tablas de contingencia no estructuradas

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2009
Loglinear models are frequently utilized in the analysis of association patterns between variables in a multidimensional contingency table. Discrete graphical models are fashionable.

Prevalence, Determinants, and Outcomes of Low Disease Activity and Remission Attainment in Patients With Systemic Lupus Erythematosus That Is Clinically Active

open access: yesArthritis Care &Research, EarlyView.
Objective This study aimed to identify in patients with systemic lupus erythematosus (SLE) with clinically active disease the attainment of frequency and determinants of Lupus Low Disease Activity State (LLDAS) and Definition of Remission in SLE (DORIS) and the frequency and determinants of flare and damage accrual after target attainment.

Experiencias con un nuevo índice de falta de ajuste en Tablas de Contingencia

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2012
Rudas, Clogg and Lindsay, en 1994, proposed a new index of lack of fit for contingency table analysis. For a contingency table P with N cells, and a model H, the new index is defined as the smallest \pi that satisfies the equation P_h=(1-\pi)\Pi_{1h ...

Bayesian factorizations of big sparse tensors [PDF]

open access: yes, 2013
It has become routine to collect data that are structured as multiway arrays (tensors). There is an enormous literature on low rank and sparse matrix factorizations, but limited consideration of extensions to the tensor case in statistics.

Association Between Symptomatic Knee Osteoarthritis and Target Glycemic Control in Individuals with Type 2 Diabetes

open access: yesArthritis Care &Research, Accepted Article.
Objective Knee osteoarthritis (OA) commonly affects individuals with Type 2 diabetes (T2DM) and is associated with increased risk of diabetes‐related complications. To better understand potential mechanisms, we examined the association between symptomatic knee OA and glycemic control in individuals with T2DM.

Use of a Molecular Signature Response Classifier to Inform Treatment Selection Improves Clinical Disease Activity Among Patients with Rheumatoid Arthritis Initiating a Biologic or Targeted Synthetic Disease‐Modifying Antirheumatic Drug

open access: yesArthritis Care &Research, EarlyView.
Objective We assessed the effectiveness of PrismRA to improve clinical outcomes among patients with rheumatoid arthritis (RA) initiating treatment with a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD). Methods PrismRA incorporated 19 gene expression features and four clinical features to assess a patient's likelihood of

Algebraic method for independence model of two-way contingency tables [PDF]

open access: yes, 2017
The main purpose of the study is to propose an algebraic method to obtain the set of all independence models of I×J two-way contingency tables with the same row sums and column sums which is called fiber in algebraic statistics.

A Latent Class Modeling Approach for Differentially Private Synthetic Data for Contingency Tables

open access: yesThe Journal of Privacy and Confidentiality, 2022
We present an approach to construct differentially private synthetic data for contingency tables. The algorithm achieves privacy by adding noise to selected summary counts, e.g., two-way margins of the contingency table, via the Geometric mechanism.

Pathological Findings in Hanging: Is the Traditional Knowledge Correct?

open access: yesDiagnostics
Background: In forensic pathology, asphyxia presents a problem as frequently as it is thorny and challenging. Some knowledge in forensic pathology is still considered to be traditionally acquired and is not critically assessed with modern statistical or ...

Profile Statistics for Sparse Contingency Tables under Poisson Sampling

open access: yesAustrian Journal of Statistics, 2016
Simple conditions for the inconsistency of classical likelihood ratio (LR) test in case of very sparse categorical data are given. The LR type test based on profile statistics is proposed as an alternative.
