A diagnostic to find and help combat stochastic positivity issues – with a focus on continuous treatments

open access: yesJournal of Causal Inference
The positivity assumption is central in the identification of a causal effect. Especially its stochastic variant is an issue many applied researchers face.

Mediation analyses for the effect of antibodies in vaccination

open access: yesJournal of Causal Inference
We review standard mediation assumptions as they apply to identifying antibody effects in a randomized vaccine trial and propose new study designs to allow the identification of an estimand that was previously unidentifiable. For these mediation analyses,

Population size estimation based on estimating functions for closed capture-recapture models

open access: yes, 2011
[[abstract]]This paper explores a unified approach to inference on the size of a closed population using capture-recapture data where time, behavior or heterogeneity may affect the capture probabilities. The unifying idea is that of an optimal estimating

Estimation of time-varying treatment effects using marginal structural models dependent on partial treatment history

open access: yesJournal of Causal Inference
Inverse probability (IP) weighting of marginal structural models (MSMs) can provide consistent estimators of time-varying treatment effects under correct model specifications and identifiability assumptions, even in the presence of time-varying ...

Stochastic modeling of group testing with random total sample size

open access: yesScientific African
In the classical Dorfman group testing procedure Dorfman (1943), a fixed population of size N is divided into k pools of equal size n . Each pool is tested: a negative result clears all n individuals, whereas a positive result triggers individual testing
