Randomizing without randomness
Economic 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.

Randomness? What Randomness? [PDF]
Foundations of Physics, 2020 AbstractThis 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. Following a (Wittgensteinian) philosophical discussion of randomness in general, I argue that deterministic interpretations of

Random walks on the random graph [PDF]
The Annals of Probability, 2018 We study random walks on the giant component of the Erdős–Rényi random graph G(n,p) where p=λ/n for λ>1 fixed. The mixing time from a worst starting point was shown by Fountoulakis and Reed, and independently by Benjamini, Kozma and Wormald, to have order log2n.

Probability Theory and Related Fields, 2023 We study how the typical gradient and typical height of a random surface are modified by the addition of quenched disorder in the form of a random independent external field. The results provide quantitative estimates, sharp up to multiplicative constants, in the following cases.

The Annals of Probability, 1996 The author proves a symmetric analog of a theorem due to Dou and Hildebrand on the expected mixing time of certain random walks on a finite group \(G\) of order \(g\) with uniform distribution \(U\), and derives from this result good bounds on diameters of random directed Cayley graphs.

Randomized graph cluster randomization
Journal 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 known to exhibit ...

The Gloria Adherence Subproject: Problems and Randomization Mistakes
Journal of Trial and Error, 2021 Medication adherence, which is the extent to which patients take their medication as prescribed, is essential in treating chronic inflammatory diseases such as rheumatoid arthritis (RA).

Randomization in Surveys with the Halton Sequence
Survey Research Methods, 2018 Randomization has been widely used in surveys for various purposes such as within household respondent selection, rotation of questions and answer choices, and split sample (or ballot) technique for survey experiments.

Frontiers in Psychology, 2021 BackgroundRandomized Controlled Trials (RCTs) are the gold standard for assessing whether an intervention is effective; however, they require large sample sizes in order to detect small effects.
