air pollution and mortality/readmission in ADRD population with Medicare data
💬 Talk on "Sensitivity Analysis for Inverse Probability Weighting Estimators via the Percentile Bootstrap" (Q. Zhao et al., 2017), for S. Pimentel's "Observational Study Design and Causal Inference" seminar at Berkeley, Spring 2018
An implementation of g-methods
A questionnaire containing 40+ questions is given to hundreds of people. People are interviewed about their feelings and hobbies with a goal to find the causal relationship between depression and cognitive impairment, where some questions are related to depression, some to cognitive impairment, and others are confounding. In psychological survey…
Optimization of KNN and Linear regression algorithms
Inverse probability weighting for non-binary exposures. Simple example in Excel and SAS.
Code for assessing the causal effects of chemotherapy Received Dose Intensity (RDI) on survival outcomes in osteosarcoma patients using a Target Trial Emulation approach.
💬 Talk on causal inference and variable importance with stochastic interventions under two-phase sampling
Non-parametric variable selection and inference via the outcome-adaptive Random Forest (OARF). Uses the IPTW estimator to estimate the ATE while the propensity score is estimated via OARF. This leads to smaller variance and bias. Only variables that are confounders or predictive of the outcome are selected for the propensity score.
Positivity violations in marginal structural survival models with time-dependent confounding: a simulation study on IPTW-estimator performance.
Tools for using marginal structural models (MSMs) to answer causal questions in developmental science.
The R package trajmsm is based on the paper Marginal Structural Models with Latent Class Growth Analysis of Treatment Trajectories: https://doi.org/10.48550/arXiv.2105.12720.
IPW- and CBPS-type propensity score reweighting, with various extensions (Stata package)
R package for estimating balancing weights using optimization
Targeted maximum likelihood estimation (TMLE) enables the integration of machine learning approaches in comparative effectiveness studies. It is a doubly robust method, making use of both the outcome model and propensity score model to generate an unbiased estimate as long as at least one of the models is correctly specified.
