Optimal precision of coarse structural nested mean models to estimate the effect of initiating ART in early and acute HIV infection

Journal of Causal Inference
Time-dependent coarse structural nested mean models (coarse SNMMs) were developed to estimate treatment effects from longitudinal observational data. Coarse SNMMs estimate the combined effect of multiple treatment dosages and are thus useful to estimate ...

Time to a single hybridization event in a group of species with unknown ancestral history

, 2012
We consider a stochastic process for the generation of species which combines a Yule process with a simple model for hybridization between pairs of co-existent species.

A causal framework for the self-controlled case series design

Journal of Causal Inference
Vaccine safety surveillance programs that monitor possible short-term rare adverse events following vaccination usually only have access to data on vaccinated individuals who experienced the event of interest.

Beyond conditional averages: Estimating the individual causal effect distribution

Journal of Causal Inference
In recent years, the field of causal inference from observational data has emerged rapidly. The literature has focused on (conditional) average causal effect estimation.

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

Journal 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.

A Gibbs approach to Chargaff's second parity rule

, 2011
Chargaff's second parity rule (CSPR) asserts that the frequencies of short polynucleotide chains are the same as those of the complementary reversed chains.
