Statistics in Service of Metascience: Measuring Replication Distance with Reproducibility Rate [PDF]

Entropy
Motivated by the recent putative reproducibility crisis, we discuss the relationship between the replicability of scientific studies, the reproducibility of results obtained in these replications, and the philosophy of statistics. Our approach focuses on

Estimating Effect Sizes and Expected Replication Probabilities from GWAS Summary Statistics [PDF]

Frontiers in Genetics, 2016
Genome-wide Association Studies (GWAS) result in millions of summary statistics (``z-scores'') for single nucleotide polymorphism (SNP) associations with phenotypes.

A replication of “A quasi-maximum likelihood approach for large, approximate dynamic factor models” (Review of Economics and Statistics, 2012) [PDF]

Economics: Journal Articles, 2020
The authors replicate and extend the Monte Carlo experiment presented in Doz, Giannone and Reichlin (A Quasi-Maximum Likelihood Approach For Large, Approximate Dynamic Factor Models, Review of Economics and Statistics, 2012) on alternative (time-domain ...

Inferential statistics as descriptive statistics: there is no replication crisis if we don't expect replication [PDF]

The American Statistician, 2018
Statistical inference often fails to replicate. One reason is that many results may be selected for drawing inference because some threshold of a statistic like the P-value was crossed, leading to biased reported effect sizes. Nonetheless, considerable non-replication is to be expected even without selective reporting, and generalizations from single ...

Statistical reform and the replication crisis [PDF]

Review of Philosophy and Psychology, 2018
The replication crisis has prompted many to call for statistical reform within the psychological sciences. Here we examine issues within Frequentist statistics that may have led to the replication crisis, and we examine the alternative---Bayesian statistics---that many have suggested as a replacement.

Statistical Physics of Self-Replication [PDF]

The Journal of Chemical Physics, 2012
Self-replication is a capacity common to every species of living thing, and simple physical intuition dictates that such a process must invariably be fueled by the production of entropy. Here, we undertake to make this intuition rigorous and quantitative by deriving a lower bound for the amount of heat that is produced during a process of self ...

Statistical Methods for Replicability Assessment [PDF]

Ann. Appl. Stat. 14(3): 1063-1087 (September 2020), 2019
Large-scale replication studies like the Reproducibility Project: Psychology (RP:P) provide invaluable systematic data on scientific replicability, but most analyses and interpretations of the data fail to agree on the definition of "replicability" and disentangle the inexorable consequences of known selection bias from competing explanations.

Replicability in High Dimensional Statistics [PDF]

arXiv
The replicability crisis is a major issue across nearly all areas of empirical science, calling for the formal study of replicability in statistics. Motivated in this context, [Impagliazzo, Lei, Pitassi, and Sorrell STOC 2022] introduced the notion of replicable learning algorithms, and gave basic procedures for $1$-dimensional tasks including ...

Improving transparency and replication in Bayesian statistics: The WAMBS-Checklist. [PDF]

Psychological Methods, 2015
Bayesian statistical methods are slowly creeping into all fields of science and are becoming ever more popular in applied research. Although it is very attractive to use Bayesian statistics, our personal experience has led us to believe that naively applying Bayesian methods can be dangerous for at least 3 main reasons: the potential influence of ...
