James Coyne pointed me with distress or annoyance to this new paper, “Tutorial: The Practical Application of Longitudinal Structural Equation Mediation Models in Clinical Trials,” by K. A. Goldsmith, D. P. MacKinnon, T. Chalder, P. D. White, M. Sharpe, and A. Pickles. This is the team behind the PACE trial for systemic exercise intolerance disease.

Plan your experiment, gather your data, do your inference for all effects and interactions of interest. When all is said and done, accept some level of uncertainty in your conclusions: you might not be 97.5% sure that the treatment effect is positive, but that’s fine. For one thing, decisions need to be made. You were […] The post On this 4th of July, let’s declare independence from “95%” appeared first…
Asher Meir points us to this post by Christie Aschwanden entitled, “Can Teamwork Solve One Of Psychology’s Biggest Problems?”, which begins: Psychologist Christopher Chartier admits to a case of “physics envy.” That field boasts numerous projects on which international research teams come together to tackle big questions. Just think of CERN’s Large Hadron Collider or […] The post The “Psychological Science Accelerator”: it’s probably a good idea but I’m still…

From today’s NYT: Another finding of note, published in the Journal of Personality and Social Psychology in 2002, is that people gravitate toward places of residence and occupations that resemble their own names. So, the researchers assert, a higher proportion of men named Louis live in St. Louis than would occur at random, and a […] The post Nooooooooooooooooo!

A graduate student in psychology writes: Grants do not fund you unless you have pilot data – and moreover – show some statistically significant finding in your N of 20 or 40 – in essence trying to convince the grant reviewers that there is “something there” worth them providing your lab lots of money to […] The post All Fools in a Circle appeared first on Statistical Modeling, Causal Inference,…

Sointu Leikas pointed us to this published research article, “Exposure to inequality affects support for redistribution.” Leikas writes that “it seems to be a really apt example of “researcher degrees of freedom.'” Here’s the abstract of the paper: As the world’s population grows more urban, encounters between members of different socioeconomic groups occur with greater […] The post Some experiments are just too noisy to tell us much of anything…
Stephen Cranney writes: For the past couple of years I have had an ongoing question/concern . . . In my fields (sociology and demography) much if not most of the published research is based on publicly available datasets; consequently, replicability is literally a simple matter of sending or uploading a few kilobytes of code text.
