Statistical Methods for Environmental Mixtures

Statistical Methods for Environmental Mixtures

Humans are simultaneously exposed to a large number of environmental hazards. To allow a more accurate identification of the risks associated with environmental exposures and developing more targeted public health interventions, it is crucial that population-based studies account for the complexity of such exposures as environmental mixtures. This poses several analytic challenges and often requires the use of extensions of standard regression approaches or more flexible techinques for high-dimensional data. This document presents an extended version of the class material that was used in an introductory two-weeks course on statistical approaches for environmental mixtures. The main challanges and limitations of standard regression techniques are outlined, and recent methodological developments are introduced in a rigorous yet non-theoretical way. The course was designed for students and postdocs in environmental health with basic preliminary knoweldge on linear and logistic regression models. Sources and code examples to conduct a thorough analysis in R are also included. Read more →

Surrogates

Surrogates: a new graduate level textbook on topics lying at the interface between machine learning, spatial statistics, computer simulation, meta-modeling (i.e., emulation), and design of experiments. Gaussian process emphasis facilitates flexible nonparametric and nonlinear modeling, with applications to uncertainty quantification, sensitivity analysis, calibration of computer models to field data, sequential design and (blackbox) optimization under uncertainty. Presentation targets numerically competent scientists in the engineering, physical, and biological sciences. Treatment includes historical perspective and canonical examples, but primarily concentrates on modern statistical methods, computation and implementation in R at modern scale. Rmarkdown facilitates a fully reproducible tour complete with motivation from, application to, and illustration with, compelling real-data examples. Read more →

STAT 331

by Ben Prytherch

2023-07-25

Ben Prytherch STAT 331, as the title states, is an “applied” statistics course. It is intended for anyone who has taken at least one introductory level statistics course, and who wants to learn more about the use of statistical methods in quantitative research. It covers many statistical tools that are usually considered too advanced for an introductory level class, but are nonetheless very popular. It also provides guidance on making data analysis decisions. Most assignments will involve looking up a published scientific paper for which the data are available and reproducing the main … Read more →

Notes for Predictive Modeling

Notes for Predictive Modeling. MSc in Big Data Analytics. Carlos III University of Madrid. [...] Welcome to the notes for Predictive Modeling. The course is part of the MSc in Big Data Analytics from Carlos III University of Madrid. The course is designed to have, roughly, one session per main topic in the syllabus. The schedule is tight due to time constraints, which will inevitably make the treatment of certain methods somehow superficial. Nevertheless, the course will hopefully give you a respectable panoramic view of different available statistical methods for predictive modeling. ... Read more →

Multivariate Statistical Analysis with R: PCA & Friends making a Hotdog

Multivariate Statistical Analysis with R: PCA & Friends making a Hotdog […] Multivariate Analysis has been developed and evolved through many iterations by many different disciplines. Virtually all scientific domains need to use statistical methods under the Multivariate umbrella to analyze data with more than 1 variable. Thus, Multivariate Analysis has gotten many names and has been customized by many “-metric” disciplines throughout the years. Overall, Multivariate Analysis explore the relationships between observations and/or variables in a multivariate dataset. The strategies commonly … Read more →
