An Introduction to R for Epidemiologists

This workshop will introduce participants to the R statistical computing platform for use in epidemiologic analysis. It is not intended to transform untested novices into R wizards in a mere half-day; rather, the goal will be to introduce the conceptual underpinnings, tools, and external resources that participants will need to overcome barriers to using R that they might encounter on their own, later. The material is designed for epidemiologists who Read more

How to make a picture worth a thousand words: Effectively communicating your research results using statistical graphics

Epidemiologists can use statistical graphics to understand our data and to guide us toward correct inferences. Well-designed graphics can also be powerful tools for communicating our study findings. However, while statistical software makes it easy to produce certain types of figures, the default options leave much to be desired. Too often, Read more

Confounding control for estimating causal effects: Looking under the hood

This workshop introduces concepts of causal inference and confounding control for causal effect estimation. We will introduce potential outcomes, and articulate the conceptual basis and assumptions for two g-methods – standardization via g-computation and inverse probability weighting. Starting with a simple point-treatment setting we will explore how these methods estimate a causal effect, comparing them to more conventional techniques such as multivariable regression and propensity score control. We will then build to the more complex Read more

An introduction to directed acyclic graphs: What you never wanted but needed to know about bias and didn’t even know to ask

This workshop will introduce participants to directed acyclic graphs (DAGs). We will review the basic principles and show how they can be used to determine appropriate sets of variables for estimating total causal effects of exposure (treatment). Participants will work through concrete examples of increasing complexity. We will also Read more

E-values, Unmeasured Confounding, Measurement Error, and Selection Bias

The workshop will consider sensitivity analysis for different forms of bias in epidemiology. It will begin with confounding, focusing on a new metric to evaluate sensitivity to unmeasured confounding called the E-value. The E-value is the minimum strength of association, on the risk ratio scale, that an unmeasured confounder would need to have with both the exposure and the outcome, conditional on the measured covariates, to fully explain away the exposure-outcome association. E-value calculations for risk ratios, outcomes differences, odds ratios, Read more

Causal Mediation: Modern Methods for Path Analysis

Causal mediation analysis can provide a mechanistic understanding of how an exposure impacts an outcome, a central goal in epidemiology and health sciences. However, rapid methodologic developments coupled with few formal courses presents challenges to implementation. Beginning with an overview of classical direct and indirect effects, this workshop will present recent advances that overcome limitations of previous methods, allowing for: (i) continuous exposures, (ii) multiple, non-independent mediators, and (iii) effects identifiable in the presence of intermediate confounders affected by exposure. Emphasis will be placed on flexible, stochastic and interventional Read more

Introduction to parametric and semi-parametric estimators for causal inference

This workshop will introduce participants to the Causal Roadmap for epidemiologic questions: 1) clear statement of the scientific question, 2) definition of the causal model and parameter of interest, 3) assessment of identifiability – that is, linking the causal effect to a parameter estimable from the observed data distribution, 4) choice and implementation of estimators including parametric and semi-parametric, and 5) interpretation of findings. The focus will be on estimation with a simple substitution estimator (parametric G-computation), inverse Read more

Causal inference for multiple time-point (longitudinal) exposures

This workshop applies the Causal Roadmap to estimate the causal effects with multiple intervention variables, such as the cumulative effect of an exposure over time and the effects on survival-type outcomes with right-censoring. We will cover longitudinal causal models, identification in the presence of time-dependent confounding, and estimation of joint treatment effects using G-computation, inverse probability weighting (IPW), and targeted maximum likelihood estimation (TMLE) with Super Learner. During the workshop session,              Read more

Targeted Learning: Causal Inference Meets Machine Learning

This workshop provides a comprehensive introduction to the field of targeted learning for causal inference, and the corresponding tlverse software ecosystem (https://github.com/tlverse). Emphasis will be placed on targeted minimum loss-based estimators of the causal effects of single timepoint interventions, including extensions for missing covariate and outcome data. These multiply robust, efficient plug-in estimators use state-of-the-art, ensemble machine learning tools to flexibly adjust for confounding while yielding valid statistical inference. In Read more

An introduction to Difference-in-Differences and Synthetic Control Methods for Epidemiologists

The interest in and use of quasi-experimental methods to evaluate the impact of a health policy or program on some disease or outcome of interest has drastically increased in the epidemiological literature. Some designs exploit the specific timing and place of an intervention implementation as a natural experiment. In this context, difference-in-differences, interrupted time series, and recent synthetic control methods have been used. In this Read more

Transportability and Data Fusion in Causal Inference Studies

It is becoming increasingly clear that producing causal estimates from studies with acceptable internal validity is not sufficient to guide interventions and policy analysis for population health. External validity is critical for applying internally valid results from a study population to a target population that may or may not have given rise to the study population. Novel developments in causal inference allow us to give the sufficient and necessary conditions for generalizability and transportability. This workshop will provide accessible theoretical and practical Read more
