On Optimal Rerandomization Designs [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2021 AbstractBlocking is commonly used in randomized experiments to increase efficiency of estimation. A generalization of blocking removes allocations with imbalance in covariate distributions between treated and control units, and then randomizes within the remaining set of allocations with balance.

Optimal design for additive partially nonlinear models [PDF]
, 2010 We develop optimal design theory for additive partially nonlinear regression models, showing that Bayesian and standardized maximin D-optimal designs can be found as the products of the corresponding optimal designs in one dimension.

Optimal Design Of English Auctions With Discrete Bid Levels [PDF]
, 2005 In this paper we consider a common form of the English auction that is widely used in online Internet auctions. This discrete bid auction requires that the bidders may only submit bids which meet some predetermined discrete bid levels and, thus, there ...

D-optimal design of experiments applied to 3D high-performance concrete printing mix design
Materials & Design, 2022 The development of 3D printable cement-based materials is a complex process with a variety of competing objectives. The compositions formed are far more complex than in conventional concrete, increasing the difficulty in designing mixtures for 3D ...

Optimal, minimax and admissible two-stage design for phase II oncology clinical trials
BMC Medical Research Methodology, 2020 Background The article aims to compare the efficiency of minimax, optimal and admissible criteria in Simon’s and Fleming’s two-stage design. Methods Three parameter settings (p 1-p 0 = 0.25–0.05, 0.30–0.10, 0.50–0.30) are designed to compare the maximum ...

A deterministic algorithm for experimental design applied to tomographic and microseismic monitoring surveys [PDF]
, 2004 Most general experimental design algorithms are either: (i) stochastic and hence give different designs each time they are run with finite computing power, or (ii) deterministic but converge to results that depend on an initial or reference design ...
