This paper analyzes the benefits and the limits of a systematic allocation of treatments within a linear model … framework. Linear models do not necessarily require the treatment allocation to be random. Since the variance of the treatment … treatment estimator and increases statistical power compared to random allocation. For a given linear model and a given effect …

This paper analyses optimal treatment allocation of experimental units to treatment and control group. 'Optimal' means … that the allocation of treatments should balance covariates across treatment and control group in a way that minimizes the … as well as the maximum benefits of this approach compared to random allocation as well as to alternative methods of …

Methods of systematically balanced treatment allocation for economic experiments, as an alternative to random … allocation, are gaining increasing attention in recent years. This paper analyzes the benefits and the limits of a systematic … allocation of treatments within a linear model framework. Linear models do not necessarily require the treatment allocation to be …
