Power analysis for concurrent balanced or imbalanced multiple-intervention stepped wedge design: a simulation-based approach

BMC Medical Research Methodology
Background The concurrent multiple-intervention stepped wedge design (M-SWD) is one of the most widely used variants of the SWD. We aimed to conduct power analysis for concurrent balanced (equal number of clusters in intervention groups) and imbalanced ...

Convex and Exact Games with Non-transferable Utility [PDF]

We generalize exactness to games with non-transferable utility (NTU). In an exact game for each coalition there is a core allocation on the boundary of its payoff set. Convex games with transferable utility are well-known to be exact.

Production-inventory games: A new class of totally balanced combinatorial optimization games [PDF]

Games Econ. Behav.
In this paper we introduce a new class of cooperative games that arise from production-inventory problems. Several agents have to cover their demand over a finite time horizon and shortages are allowed.

Randomization in clinical trials with small sample sizes using group sequential designs.

PLoS ONE
BackgroundGroup sequential designs, which allow early stopping for efficacy or futility, may benefit from balanced sample sizes at interim and final analyses. This requirement for balance limits the choice of admissible randomization procedures.
