Wellcome Open Research, 2020 Protocol non-adherence is common and poses unique challenges in the interpretation of trial outcomes, especially in non-inferiority trials. We performed simulations of a non-inferiority trial with a time-fixed treatment and a binary endpoint in order to:

The Augmented Synthetic Control Method
, 2020 The synthetic control method (SCM) is a popular approach for estimating the impact of a treatment on a single unit in panel data settings. The "synthetic control" is a weighted average of control units that balances the treated unit's pre-treatment ...

Assessing the effect of longitudinal multiple subsidies on firm performance in the presence of neighbour interactions: A case study in the hotel industry [PDF]
, 2015 A Structural Marginal Model and Inverse Probability of Treatment Weighting (IPTW) estimation strategy is proposed in a dynamic 2-dimensional treatment setting in order to identify and estimate both the direct and the indirect average treatment effects of

Variance Estimation for the Inverse Probability of Treatment Weighted Kaplan Meier Estimator
In a widely cited paper, Xie and Liu (henceforth XL) proposed to use inverse probability of treatment weighting (IPTW) to account for possible confounding in observational studies with survival endpoints subject to right censoring. Their proposal includes an IPTW Kaplan-Meier (KM) estimator for the survival function of a treatment-specific potential ...

Sequential Matching Estimation of Dynamic Causal Models [PDF]
This paper proposes sequential matching and inverse selection probability weighting to estimate dynamic casual effects. The sequential matching estimators extend simple, matching estimators based on propensity scores for static causal analysis that have ...
