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.

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 ...

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

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.

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 ...

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

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

The new normal? Redaction bias in biomedical science

Royal Society Open Science, 2021
A concerning amount of biomedical research is not reproducible. Unreliable results impede empirical progress in medical science, ultimately putting patients at risk.
