摘要:In this study we focus on Cooperative Differential Network Learning with hub detection (CDNL) for functional Magnetic Resonance Imaging (fMRI) scan from multiple research centers. As research centers may use varying scanners, imaging parameters, and other conditions that introduce heterogeneity, CDNL allows us to analyze fMRI data from various perspectives while identifying shared structures, potentially revealing the underlying mechanisms of neurological diseases. In addition, brain functiona...

摘要:The Frequency Modulated M & ouml;bius (FMM) approach is a contemporary and versatile tool for analyzing oscillatory signals. Within the functional data analysis framework, the FMM model offers an accurate alternative for comprehending multidimensional synchronized oscillatory signals, which are common in various fields including biology and medicine. This approach decomposes the signals into scaled M & ouml;bius waves formulated in terms of four parameters, interpreted as measures of location ...

摘要:The causal link between victimization and violence later in life is largely accepted but has been understudied for victimized adolescents. In this work we use the Add Health dataset, the largest nationally representative longitudinal survey of adolescents, to estimate the relationship between victimization and future offending in this population. To accomplish this, we derive a new doubly robust estimator for the average treatment effect on the treated (ATT) when the exposure and outcome are n...

摘要:The microbiome has been found to have a close relationship with human health. Advancements in sequencing technologies have enabled in-depth studies of microbial communities and their associations with various diseases. When analyzing microbiome data, it is common to perform compositional scale normalization to ensure statistical validity. This requires special treatment to address the unique characteristics of microbiome data. Furthermore, biomedical studies often involve repeated measurements...

摘要:The identification of genetic signal regions in the human genome is critical for understanding the genetic architecture of complex traits and diseases. Numerous methods based on scan algorithms (i.e., QSCAN, SCANG, SCANG-STAAR) have been developed to allow dynamic window sizes in whole-genome association studies. Beyond scan algorithms, we have recently developed the binary and research (BiRS) algorithm, which is more computationally efficient than scan-based methods and exhibits superior stat...

摘要:Runway overruns pose a significant challenge to aviation safety and represent the most common type of landing incident. Identifying the underlying factors contributing to runway overruns is vital for the development of effective prevention strategies. Since a few overruns are observed, the distance required for a pilot to achieve control of the aircraft, measured by the distance to decelerate to 80 knots, is used as a precursor. We propose vine copulabased distributional regression models for ...

摘要:Sepsis is a life-threatening condition affecting millions of individuals in the U.S. each year. The complexity of sepsis clinical management makes individualized treatment approaches desirable. The University of Pittsburgh Medical Center (UPMC) has collected electronic health records data of sepsis patients from multiple hospitals. The goal of this study is to derive individualized decision rules (IDRs) that could be safely applied to and uniformly improve decision-making across hospitals in t...

摘要:Wildlife population surveys typically consist of multiple sampling occasions, where individuals are followed over time, enabling estimation of population size and, in open populations, of entry and exit patterns. Batch-mark (BM) surveys, where newly sampled individuals are given the same marking, often unique for each sampling occasion or each sampling period but not for each individual, provide the only viable monitoring tool for many species of amphibians, birds and fish. Modelling BM data f...

摘要:Exposure indices measure the degree of contact between two groups and are used to quantify occupational discrepancies between genders in a set of occupational sectors. This paper presents a novel methodology for predicting area-level proportions of employed men and women across various occupation sectors, along with estimating exposure indexes. The challenge arises from the compositional nature of the direct estimators of proportions, which tend to be imprecise when sample sizes are small. To ...

摘要:The social characteristics of players in a social network are closely associated with their network positions and relational importance. Identifying those influential players in a network is of great importance, as it helps to understand how ties are formed, how information is propagated, and, in turn, can guide the dissemination of new information. Motivated by a Sina Weibo social network analysis of the 2021 Henan Floods, where response variables for each Sina Weibo user are available, we pr...
