1:28 PM | When doing scientific replication or criticism, collaboration with the original authors is fine but I don’t think it should be a requirement or even an expectation
Dominik Papies points me to this article, “Matched-Names Analysis Reveals No Evidence of Name-Meaning Effects,” by psychologist and data detective Uri Simonsohn, in collaboration with Raphael Silberzahn and Eric Luis Uhlmann, the two authors of an earlier study that this new report is refuting. Papies writes: This seems to me an interesting case where a […] The post When doing scientific replication or criticism, collaboration with the original authors is fine but I […]

3:26 PM | Correlation does not even imply correlation
The above title is my response to a discussion that began with this email sent to be by Steve Roth: Noah Smith had a great tweet recently, a real keeper for me [Roth]. Causation is correlated with correlation. I would reword it: Correlation correlates with causation. (Just not very much.) And I wonder if the […] The post Correlation does not even imply correlation appeared first on Statistical Modeling, Causal Inference, and Social Science.

8:15 AM | I Love You To Bits: Female Sex Cannibalism and Male Counter-Adaptation in the Redback Spider
The redback spider (Latrodectus hasselti) is a nocturnal venomous spider found in Australia which displays sexual cannibalism during mating. Female Sex Cannibalism and Post-Copulatory Paternity Choices For the female, killing the male is not such a big deal because she can easily raise the offspring on her own and is able to store the sperm in her reproductive tract called spermathecae for as long as two years to fertilize its eggs later. Females mate with multiple males and research has... […]

7:48 AM | What Homeland has to do with causal inference in process tracing
More often than one might expect, television series and films offer excellent illustrations of methodological and methods-related arguments (which is worth a blog post of its own). When I was working on my paper on comparative hypothesis testing in process … Continue reading →

1:12 PM | The “scientific surprise” two-step
During the past year or so, we’ve been discussing a bunch of “Psychological Science”-style papers in which dramatic claims are made based on somewhat open-ended analysis of small samples with noisy measurements. One thing that comes up in some of these discussions is that the people performing the studies say that they did not fish […] The post The “scientific surprise” two-step appeared first on Statistical Modeling, Causal Inference, and Social Science.

10:11 PM | Stanny Stanny Stannitude
On the stan-users list, Richard McElreath reports: With 2.4 out, I ran a quick test of how much speedup I could get by changing my old non-vectorized multi_normal sampling to the new vectorized form. I get a 40% time savings, without even trying hard. This is much better than I expected. Timings with vectorized multi_normal: […] The post Stanny Stanny Stannitude appeared first on Statistical Modeling, Causal Inference, and Social Science.

6:25 PM | On the Road: The Evolution of HIV Along Highway Networks
Just as we jetsetters and nomads wander the wide world’s winding roads and byways by foot, on horseback, atop a bicycle or packed into an automobile, so too do infectious diseases make use of our ever-improving networks of thoroughfares. They ride along in human bodies, their journeys fueled by our social mobility and contact, two […]The post On the Road: The Evolution of HIV Along Highway Networks appeared first on Body Horrors.

1:34 PM | The health policy innovation center: how best to move from pilot studies to large-scale practice?
A colleague pointed me to this news article regarding evaluation of new health plans: The Affordable Care Act would fund a new research outfit evocatively named the Innovation Center to discover how to most effectively deliver health care, with $10 billion to spend over a decade. But now that the center has gotten started, many […] The post The health policy innovation center: how best to move from pilot studies to large-scale practice? appeared first on Statistical Modeling, Causal […]
