The average treatment effect and average partial effect in nonlinear models [PDF]

open access: yes, 2007
In the literature on program impact evaluation, the popular impact parameters can the average treatment effect, the average treatment effect on the treated, the average partial effect, and the average partial effect on the treated. In empirical studies, these parameters are not always presented and estimated clearly. In addition, when outcome functions

On estimating average effects for multiple treatment groups

Statistics in Medicine, 2012
We propose to estimate average exposure (or treatment) effects from observational data for multiple exposure groups by fitting an approximation of the marginal sample distribution of the response variable in each exposure group to the data. The marginal sample distribution is a function of the true distribution of the response variable in the ...

Model averaging for treatment effect estimation in subgroups

Pharmaceutical Statistics, 2016
AbstractIn many clinical trials, biological, pharmacological, or clinical information is used to define candidate subgroups of patients that might have a differential treatment effect. Once the trial results are available, interest will focus on subgroups with an increased treatment effect.

Subclassification estimation of the weighted average treatment effect

Biometrical Journal, 2021
AbstractWeighting and subclassification are popular approaches using propensity scores (PSs) for estimation of causal effects. Weighting is appealing in that it gives consistent estimators for various causal estimands if appropriate weights are well defined and the PS model is correctly specified.

The Sample Average Treatment Effect

2018
In cluster randomized trials (CRTs), the study units usually are not a simple random sample from some clearly defined target population. Instead, the target population tends to be hypothetical or ill-defined, and the selection of study units tends to be systematic, driven by logistical and practical considerations.

Propensity scores based methods for estimating average treatment effect and average treatment effect among treated: A comparative study

Biometrical Journal, 2017
Propensity score based statistical methods, such as matching, regression, stratification, inverse probability weighting (IPW), and doubly robust (DR) estimating equations, have become popular in estimating average treatment effect (ATE) and average treatment effect among treated (ATT) in observational studies.
