Budget Feasible Mechanisms for Experimental Design

, 2013
In the classical experimental design setting, an experimenter E has access to a population of $n$ potential experiment subjects $i\in \{1,...,n\}$, each associated with a vector of features $x_i\in R^d$.

Adaptive Experimental Design Using the Propensity Score [PDF]

Many social experiments are run in multiple waves, or are replications of earlier social experiments. In principle, the sampling design can be modified in later stages or replications to allow for more efficient estimation of causal effects.

Study designs: Part 4 – Interventional studies

Perspectives in Clinical Research, 2019
In the fourth piece of this series on research study designs, we look at interventional studies (clinical trials). These studies differ from observational studies in that the investigator decides whether or not a participant will receive the exposure (or
