Precision-based designs for sequential randomized experiments
Mattias Nordin, Mårten Schultzberg
In this paper, we consider an experimental setting where units enter the experiment sequentially. Our goal is to form stopping rules which lead to estimators of treatment effects w…

Inference in experiments conditional on observed imbalances in covariates
Per Johansson, Mattias Nordin
Double blind randomized controlled trials are traditionally seen as the gold standard for causal inferences as the difference-in-means estimator is an unbiased estimator of the ave…

Properties of restricted randomization with implications for experimental design
Mattias Nordin, Mårten Schultzberg
Recently, there as been an increasing interest in the use of heavily restricted randomization designs which enforces balance on observed covariates in randomized controlled trials.…
