Statistical Analysis of a Hybrid Replication Model [PDF]
, 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]
Cell, 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

Defining Replicability of Prediction Rules [PDF]
arXiv, 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.

Frontiers 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

Does it actually feel right? A replication attempt of the rounded price effect [PDF]
Royal Society Open Science, 2018 How does the roundedness of prices affect product evaluations? The ‘rounded price effect’ postulates that depending on the context, rounded or non-rounded prices increase the purchase likelihood of consumers.

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

Frontiers in Psychiatry, 2023 A core principle in the pursuit of scientific knowledge is that science is self-correcting and that important results should be replicable. Hypotheses need to be reinforced, adjusted, or rejected when novel results are obtained.

Modeling and replicating statistical topology and evidence for CMB nonhomogeneity [PDF]
Proceedings of the National Academy of Sciences, 2017 SignificanceUnder the general heading of “topological data analysis” (TDA), the recent adoption of topological methods for the analysis of large, complex, and high-dimensional data sets has established that the abstract concepts of algebraic topology provide powerful tools for data analysis. However, despite the successes of TDA, most applications have

Statistical Assessment of Replicability via Bayesian Model Criticism [PDF]
arXiv, 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 ...

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