Now when I look at my old R code, it looks really weird because there are no semicolons. What’s with that? The post Exposure to Stan has changed my defaults appeared first on Statistical Modeling, Causal Inference, and Social Scienc...
Is Rigor Contagious? Much of the theory and practice of statistics and econometrics is characterized by a toxic mixture of rigor and sloppiness. Methods are justified based on seemingly pure principles that can’t survive reality. Examples...Show More Summary
(Aalto University) In a recent study combining machine learning and bioinformatics, a new computational method was developed for modelling gene transfers between different lineages of a bacterial population or even between entirely different bacterial species. The method was used to analyze a collection of 616 whole-genomes of a recombinogenic pathogen Streptococcus pneumoniae.
I have a post coming on 2 Mar on preregistration that I think you’ll like. It unifies some ideas regarding statistical design and analysis, and in some ways it’s a follow-up to my Borscht Belt post. The post Note to Deborah Mayo appeared first on Statistical Modeling, Causal Inference, and Social Science.

I firmly believe that the general principles of social science can improve our understanding of the world. Today I want to talk about two principles—division of labor from economics, and roles from sociology—and their relevance to the...Show More Summary
(Okinawa Institute of Science and Technology (OIST) Graduate University) New research supports a structure-based classification system for viruses which could help in the identification and treatment of emerging viruses.
(University of York) Scientists at the Universities of York, Leeds, and Helsinki say they are a step closer to cracking, what researchers have dubbed, the 'enigma code' of the common cold virus.
(Utah State University) Resource management boundaries seldom align with environmental systems, which can lead to scale mismatch or spatial misalignments. Researchers Jesse Sayles of McGill University and Jacopo Baggio of Utah StateShow More Summary

(University of Rochester) University of Rochester computer scientists were able to shed light on how Trump won the presidential election by using data science to track the millions of Twitter followers who liked or 'unliked' the candidates throughout the campaign.
For Sylvia Serfaty, mathematics is all about truth and beauty and building scientific and human connections.
Looking for Rigor in All the Wrong Places What do the following ideas and practices have in common: unbiased estimation, statistical significance, insistence on random sampling, and avoidance of prior information? All have been embraced as ways of enforcing rigor but all have backfired and led to sloppy analyses and erroneous inferences. Show More Summary
(University of Tsukuba) University of Tsukuba researchers developed an approach to measure the amount of active drag from the water to which swimmers are subjected. The approach involves connecting swimmers in a water flume to load cells in front of and behind them, to characterize the forward and backward forces they exert at different flow rates.

I happened to come across this article and it reminded me of the general point that it’s possible to behave unethically without being a “bad guy.” The story in question involves some scientists who did some experiments about thirty years ago on the biological effects of low-frequency magnetic fields.
