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.

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.

Statistical Inference 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 ...

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 ...

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

Do group ensemble statistics bias visual working memory for individual items? A registered replication of Brady and Alvarez (2011) [PDF]

Attention, perception & psychophysics, 2020
We performed a registered and precise replication of Experiment 1 reported in Brady and Alvarez ( Psychological Science , 22 , 384–392, 2011 ). The original experiment found that participants, who were asked to memorize the size of differently colored ...

New statistical metrics for multisite replication projects [PDF]

Journal of the Royal Statistical Society Series A: Statistics in Society, 2020
Increasingly, researchers are attempting to replicate published original studies by using large, multisite replication projects, at least 134 of which have been completed or are on going.

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 ...

The Statistics of Replication

Methodology, 2019
. 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.

Leveraging Genomic Annotations and Pleiotropic Enrichment for Improved Replication Rates in Schizophrenia GWAS.

PLoS Genetics, 2016
Most of the genetic architecture of schizophrenia (SCZ) has not yet been identified. Here, we apply a novel statistical algorithm called Covariate-Modulated Mixture Modeling (CM3), which incorporates auxiliary information (heterozygosity, total linkage ...
