It is commonly reported that rare variants may be more functionally related to complex diseases than common variants. However, individual rare variant association tests remain challenging due to low minor allele frequency in the available samples. This paper proposes an expectation maximization variable selection (EMVS) method to simultaneously detect common and rare variants at the individual variant level using family trio data.

Functional concurrent, or varying-coefficient, regression models are a form of functional data analysis methods in which functional covariates and outcomes are collected concurrently. Two active areas of research for this class of models are identifying influential functional covariates and clustering their relations across observations. In various applications, researchers have applied and developed methods to address these objectives separately.

Article Synopsis
  • - This study assessed cognitive performance in adults and adolescents with Down syndrome (DS) and non-specific intellectual disability (NSID) to see how their crystallized intelligence (Gc) and fluid intelligence (Gf) vary across ages and conditions.
  • - Results showed that adults scored higher than adolescents in most tests, supporting the idea that cognitive performance improves with age, while adults with DS had more coherent connections between Gc and Gf compared to those with NSID.
  • - The findings suggest that individuals with DS exhibit a relatively stronger cognitive profile, indicating potential for continued growth and development in adulthood, which may help protect against future cognitive decline.

Integrated models are a popular tool for analyzing species of conservation concern. Species of conservation concern are often monitored by multiple entities that generate several datasets. Individually, these datasets may be insufficient for guiding management due to low spatio-temporal resolution, biased sampling, or large observational uncertainty.

Analyzing multivariate count data generated by high-throughput sequencing technology in microbiome research studies is challenging due to the high-dimensional and compositional structure of the data and overdispersion. In practice, researchers are often interested in investigating how the microbiome may mediate the relation between an assigned treatment and an observed phenotypic response. Existing approaches designed for compositional mediation analysis are unable to simultaneously determine the presence of direct effects, relative indirect effects, and overall indirect effects, while quantifying their uncertainty.
