The Role of Random Allocation in Randomized Controlled Trials: Distinguishing Selection Bias from Baseline Imbalance

Journal of MultiDisciplinary Evaluation, 2013
Background: This paper addresses one threat to the internal validity of a randomized controlled trial (RCT), selection bias. Many authors argue that random allocation is used to ensure baseline equality between study conditions in a given study and ...

Comparison of sampling effort allocation strategies in a stratified random survey with multiple objectives

Aquaculture and Fisheries, 2020
Stratified random survey is commonly used to estimate abundance indices of fish populations in multispecies survey, providing reliable data for stock assessment and fisheries management. In some cases, however, the sample size is relatively small because

Sequential-choice Random Allocation: An Efficient Process for Matching Students to Mentorships, Job Shadowing and Other Short-Term Experiential Opportunities

Journal for Advancement of Marketing Education, 2021
## Purpose of the Study Resource allocation is more than the matching of two objects, but a systematic and efficient pairing process. Some experiential learning activities, like job-shadow assignments may create matching problems that can be solved with

An Underwater Cooperative Spectrum Sharing Protocol for a Centralized Underwater Cognitive Acoustic Network

Sensors, 2022
To efficiently utilize nonexclusive underwater acoustic frequencies, we propose an Underwater Cooperative Spectrum Sharing (UCSS) protocol for a centralized underwater cognitive acoustic network that mainly consists of two parts.

Pricing Randomized Allocations

Proceedings of the Twenty-First Annual ACM-SIAM Symposium on Discrete Algorithms, 2010
Randomized mechanisms, which map a set of bids to a probability distribution over outcomes rather than a single outcome, are an important but ill-understood area of computational mechanism design. We investigate the role of randomized outcomes (henceforth, "lotteries") in the context of a fundamental and archetypical multi-parameter mechanism design ...

Redundancy Allocation of Partitioned Linear Block Codes

, 2013
Most memories suffer from both permanent defects and intermittent random errors. The partitioned linear block codes (PLBC) were proposed by Heegard to efficiently mask stuck-at defects and correct random errors.

Using an incomplete block design to allocate lines to environments improves sparse genome‐based prediction in plant breeding

The Plant Genome, 2022
Genomic selection (GS) is a predictive methodology that trains statistical machine‐learning models with a reference population that is used to perform genome‐enabled predictions of new lines.

5G green cellular networks considering power allocation schemes

, 2015
It is important to assess the effect of transmit power allocation schemes on the energy consumption on random cellular networks. The energy efficiency of 5G green cellular networks with average and water-filling power allocation schemes is studied in ...
