Hypothesis-Testing Demands Trustworthy Data—A Simulation Approach to Inferential Statistics Advocating the Research Program Strategy

open access: yesFrontiers in Psychology, 2018
In psychology as elsewhere, the main statistical inference strategy to establish empirical effects is null-hypothesis significance testing (NHST). The recent failure to replicate allegedly well-established NHST-results, however, implies that such results

Replicable Reinforcement Learning [PDF]

open access: yesarXiv, 2023
The replicability crisis in the social, behavioral, and data sciences has led to the formulation of algorithm frameworks for replicability -- i.e., a requirement that an algorithm produce identical outputs (with high probability) when run on two different samples from the same underlying distribution.

Defining Replicability of Prediction Rules [PDF]

open access: yesarXiv, 2023
In this article I propose an approach for defining replicability for prediction rules. Motivated by a recent NAS report, I start from the perspective that replicability is obtaining consistent results across studies suitable to address the same prediction question, each of which has obtained its own data.

The Statistics of Replication

open access: yesMethodology, 2019
Abstract. The concept of replication is fundamental to the logic and rhetoric of science, including the argument that science is self-correcting. Yet there is very little literature on the methodology of replication. In this article, I argue that the definition of replication should not require underlying effects to be identical, but should permit ...

Statistical Analysis of a Hybrid Replication Model [PDF]

open access: yes, 2002
Replication is a technique commonly used to provide high-availability and fault tolerance in distributed systems. With multiple copies of the entities, a service can keep operation even when some copies are inaccessible because of a crash of the computer where a copy was stored, for instance.

Contingency and Statistical Laws in Replicate Microbial Closed Ecosystems [PDF]

open access: yesCell, 2012
Contingency, the persistent influence of past random events, pervades biology. To what extent, then, is each course of ecological or evolutionary dynamics unique, and to what extent are these dynamics subject to a common statistical structure? Addressing this question requires replicate measurements to search for emergent statistical laws. We establish

Kontrola tačnosti rezultata u simulacijama Monte Karlo / Accuracy control in Monte Carlo simulations

open access: yesVojnotehnički Glasnik, 2010
U radu je demonstrirana primena metode automatizovanog ponavljanja nezavisnih simulacionih eksperimenata sa prikupljanjem statistike slučajnih procesa, u dostizanju i kontroli tačnosti simulacionih rezultata u simulaciji sistema masovnog opsluživanja ...

Statistical Assessment of Replicability via Bayesian Model Criticism [PDF]

open access: yesarXiv, 2021
Assessment of replicability is critical to ensure the quality and rigor of scientific research. In this paper, we discuss inference and modeling principles for replicability assessment. Targeting distinct application scenarios, we propose two types of Bayesian model criticism approaches to identify potentially irreproducible results in scientific ...

How Xenopus laevis replicates DNA reliably even though its origins of replication are located and initiated stochastically [PDF]

open access: yesPhys. Rev. Lett. 98, 098105 (2007), 2006
DNA replication in Xenopus laevis is extremely reliable, failing to complete before cell division no more than once in 10,000 times; yet replication origins sites are located and initiated stochastically. Using a model based on 1d theories of nucleation and growth and using concepts from extreme-value statistics, we derive the distribution of ...

Non-stationary Markovian Replication Process causing Diverse Diffusions [PDF]

open access: yesPhys. Rev. E 96, 042144 (2017), 2017
We introduce a single generative mechanism with which it is able to describe diverse non-stationary diffusions. A non-stationary Markovian replication process for steps is considered, for which we analytically derive time-evolution of the probability distribution of the walker's displacement and the generalized telegrapher equation with time-varying ...
