摘要:In the information age, it has become increasingly common for data containing records about overlapping individuals to be distributed across multiple sources, making it necessary to identify which records refer to the same individual. The goal of record linkage is to estimate this unknown structure in the absence of a unique identifiable attribute. We introduce a Bayesian hierarchical record linkage model for spatial location data motivated by the estimation of individual-specific growth-size ...

摘要:Brain connectivity characterizes interactions between different regions of a brain network during resting-state or performance of a cognitive task. In studying brain signals, such as electroencephalograms (EEG), one formal approach to investigating connectivity is through an information-theoretic causal measure called transfer entropy (TE). To enhance the functionality of TE in brain signal analysis, we propose a novel methodology that captures cross-channel information transfer in the frequen...

摘要:To study the neurophysiological basis of attention deficit hyperactivity disorder (ADHD), clinicians use electroencephalography (EEG) which records neuronal electrical activity on the cortex. Instead of focusing on single-channel spectral power, a novel framework for investigating interactions (dependence) between channels in the entire network is proposed. Although dependence measures, such as coherence and partial directed coherence (PDC), are well explored in studying brain connectivity, th...

摘要:Educational assessments are valuable tools for measuring student knowledge and skills, but their validity can be compromised when test takers exhibit changes in response behavior due to factors such as time pressure. To address this issue, we introduce a novel latent factor model with change-points for item response data, designed to detect and account for individual-level shifts in response patterns during testing. This model extends traditional item response theory (IRT) by incorporating per...

摘要:The diagnosis and treatment of cancer can evoke a variety of adverse emotions. Online health communities (OHCs) provide a safe platform for cancer patients and those closely related to express emotions without fear of judgement or stigma. In the literature, linguistic analysis of OHCs is usually limited to a single disease and based on methods with various technical limitations. In this article we analyze posts from September 2003 to September 2022 on eight cancers that are publicly available ...

摘要:Addressing misreporting of participation in social programs, which is common and has increased in all major surveys, is important to study inter-generational effects of policies. In this paper we propose a practical estimator for a quantile regression model with endogenous one-sided misreporting. The identification of the model uses a parametric first stage and information related to participation and misreporting. We show that the estimator is consistent and asymptotically normal. We also est...

摘要:Dementia is globally one of the leading causes of death and the primarycause of dependency and disability in senior citizens. Life expectancy withdementia, defined as the average remaining lifespan for cases with dementia,is a key epidemiological concept in geriatrics. In spite of its significance formedical research and policy-making, this measure has not been studied forpeople with dementia in the Canadian population. We employ data from theCanadian Study of Health and Aging, a nationwide cr...

摘要:Forecasting and controlling PM2.5 emissions is crucial for environmental protection and public health. To analyze the Beijing multisite air quality dataset on regional and seasonal effects in PM2.5 emissions, which has large-scale distributed cluster/longitudinal data and high-dimensional covariates, we develop a unified cluster subsampling method for generalized linear models (GLMs) to downsize the data volume and reduce computational burden. To incorporate the within-subject correlation, a w...

摘要:Atherosclerosis is a chronic, multifaceted disease that affects multiple arterial systems. Its progression is primarily driven by low-density lipopro-tein (LDL) cholesterol accumulation, which promotes localized arterial le-sion formation. These lesions can lead to severe complications, including is-chemic heart disease (IHD) and stroke. Both genetic factors, particularly sin-gle nucleotide polymorphisms (SNPs), and age-related changes in body com-position significantly influence LDL levels, g...

摘要:Estimating the joint effect of a multivariate, continuous exposure is crucial, particularly in environmental health where interest lies in simultaneously evaluating the impact of multiple environmental pollutants on health. We develop novel methodology that addresses two key issues for estimation of treatment effects of multivariate, continuous exposures. We use nonparametric Bayesian methodology that is flexible to ensure our approach can capture a wide range of data generating processes. Add...
