Stata's structural equation modeling (SEM) capabilities have been greatly expanded in version 13. Support for categorical and count outcomes as well as multilevel data structures allow us to fit a dizzying array of models. This talk will demonstrate how to use these new features with several...

In this talk, I will provide an overview of Stata features that are typically used for the analysis of psychometric and educational testing data. Traditional multivariate tools such as canonical correlation, MANOVA, multivariate regression, Cronbach’s alpha, exploratory and confirmatory...

Modern genetic genome-wide association studies (GWAS) typically rely on single nucleotide polymorphism (SNP) chip technology to determine hundreds of thousands of genotypes for an individual sample. Once these genotypes are ascertained, each SNP alone or combination is tested for association...

Project Heartbeat! was a longitudinal study of metabolic and morphological changes in adolescents aged 8–18 years and was conducted in the 1990s. A study is currently being conducted to consider the relationship between a collection of phenotypes (including BMI, blood pressure, and blood...

Abstract genetic association studies often explore the relationship between diseases and collections of contiguous genetic markers located on the same chromosome (known as haplotypes). Haplotypes are usually not observed directly but are inferred statistically using a variety of algorithms. One...
