Kort om boken
Om Nonparametric Models for Longitudinal Da
Nonparametric Models for Longitudinal Data with Implementations in R presents a comprehensive summary of major advances in nonparametric models and smoothing methods with longitudinal data. It covers methods, theories, and applications that are particularly useful for biomedical studies in the era of big data and precision medicine. It also provides flexible tools to describe the temporal trends, covariate effects and correlation structures of repeated measurements in longitudinal data. This book is intended for graduate students in statistics, data scientists and statisticians in biomedical sciences and public health. As experts in this area, the authors present extensive materials that are balanced between theoretical and practical topics. The statistical applications in real-life examples lead into meaningful interpretations and inferences. Features:Provides an overview of parametric and semiparametric methods Shows smoothing methods for unstructured nonparametric modelsCovers structured nonparametric models with time-varying coefficientsDiscusses nonparametric shared-parameter and mixed-effects modelsPresents nonparametric models for conditional distributions and functionalsIllustrates implementations using R software packagesIncludes datasets and code in the authors' websiteContains asymptotic results and theoretical derivationsBoth authors are mathematical statisticians at the National Institutes of Health (NIH) and have published extensively in statistical and biomedical journals.
