Randomizing without randomness

open access: yesEconomic Theory, 2022
AbstractWe provide a methodology for eliciting utility midpoints from preferences, assuming that payoffs are consumption plans and that preferences satisfy a minimal form of additive separability. The methodology does not require any subjective or objective uncertainty.

Randomized graph cluster randomization

open access: yesJournal of Causal Inference, 2023
Abstract The global average treatment effect (GATE) is a primary quantity of interest in the study of causal inference under network interference. With a correctly specified exposure model of the interference, the Horvitz–Thompson (HT) and Hájek estimators of the GATE are unbiased and consistent, respectively, yet

Randomness? What Randomness? [PDF]

open access: yesFoundations of Physics, 2020
Abstract This is a review of the issue of randomness in quantum mechanics, with special emphasis on its ambiguity; for example, randomness has different antipodal relationships to determinism, computability, and compressibility.

Randomization-Based Inference for Clinical Trials with Missing Outcome Data

open access: yes, 2023
Randomization-based inference is a natural way to analyze data from a clinical trial. But the presence of missing outcome data is problematic: if the data are removed, the randomization distribution is destroyed and randomization tests have no validity ...

Random Trees in Random Graphs [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
We show that a random labeled n n -vertex graph almost surely contains isomorphic copies of almost all labeled

Sampling-Based Robot Motion Planning: A Review

open access: yesIEEE Access, 2014
Motion planning is a fundamental research area in robotics. Sampling-based methods offer an efficient solution for what is otherwise a rather challenging dilemma of path planning.

Fatty Acid Sentinels as Covalently Bound Randomization Standards for Triacylglycerol (TAG) Quantitative Analysis [PDF]

open access: yes, 2020
RATIONALE. Quantitative analysis of triacylglycerols (TAG) is impeded by a lack of standards and the huge number of potential TAG molecular species that may be present due to the combinatorial nature of glycerolipids.

A random shock is not random assignment [PDF]

open access: yesEconomics Letters, 2016
A random shock excludes reverse causality and reduces omitted variable bias. Yet a natural experiment does not identify random exposure to treatment, but the reaction to a random change from baseline to treatment. A lab experiment comparing higher certainty with higher severity of punishment for stealing (holding the expected value of the intervention ...

The randomized communication complexity of randomized auctions [PDF]

open access: yesProceedings of the 53rd Annual ACM SIGACT Symposium on Theory of Computing, 2021
We study the communication complexity of incentive compatible auction-protocols between a monopolist seller and a single buyer with a combinatorial valuation function over $n$ items. Motivated by the fact that revenue-optimal auctions are randomized [Tha04,MV10,BCKW10,Pav11,HR15] (as well as by an open problem of Babaioff, Gonczarowski, and Nisan ...

Randomization in clinical studies [PDF]

open access: yesKorean Journal of Anesthesiology, 2019
Randomized controlled trial is widely accepted as the best design for evaluating the efficacy of a new treatment because of the advantages of randomization (random allocation).
