Stan attribution

I worry that I get too much credit for Stan. So let me clarify. I didn’t write Stan. Stan is written in C++, and I’ve never in my life written a line of C, or C+, or C++, or C+++, or C-, or any of these things.

Uri Simonsohn warns us not to be falsely reassured

I agree with Uri Simonsohn that you don’t learn much by looking at the distribution of all the p-values that have appeared in some literature. Uri explains: Most p-values reported in most papers are irrelevant for the strategic behavior of interest. Covariates, manipulation checks, main effects in studies testing interactions, etc. Including them we underestimate […] The post Uri Simonsohn warns us not to be falsely reassured appeared first on…

New paper on psychology replication

The Open Science Collaboration, a team led by psychology researcher Brian Nosek, organized the replication of 100 published psychology experiments. They report: A large portion of replications produced weaker evidence for the original findings despite using materials provided by the original authors, review in advance for methodological fidelity, and high statistical power to detect the […] The post New paper on psychology replication appeared first on Statistical Modeling, Causal Inference,…

The way it works is that it visualizes the entire world’s economic output as a circle. That circle is then subdivided […] The post Vizzy vizzy vizzy viz appeared first on Statistical Modeling, Causal Inference, and…

By

Deborah Mayo writes: I’m very curious as to how you would answer this for subjective Bayesians, at least. I found this section of my book showed various positions, not in agreement. I responded on her blog: As we discuss in BDA and elsewhere, one can think of one’s statistical model, at any point in time, […] The post “Can you change your Bayesian prior?” appeared first on Statistical Modeling, Causal…
