A Link Between theE-Value and the Robustness of Block Designs
研究了二元不完全区组设计在观测数据丢失时保持连通性的稳健性，建立了计划设计的E值与可容忍观测丢失程度之间的联系，并提供了简单界限帮助实践者评估设计稳健性。
This article investigates the robustness of binary incomplete block designs against giving rise to a disconnected design in the event of observation loss. A link is established between the E-value of a planned design and the extent of observation loss that can be experienced while still guaranteeing an eventual design from which all treatment contrasts can be estimated. Patterns of missing observations covered include loss of entire blocks and loss of individual observations. Simple bounds are provided enabling practitioners to easily assess the robustness of a planned design.
