In my opinion, batch effects are the biggest challenge faced by genomics research, especially in precision medicine. As we point out in this review, they are everywhere among high-throughput experiments. But batch effects are not specific to genomics technology. In fact, in this 1972 paper (paywalled), WJ Youden describes batch effects in the context of measurements made by physicists.

There has been a lot of recent interest from scientific journals and from other folks in creating checklists for data science and data analysis. The idea is that the checklist will help prevent results that won't reproduce or replicate from the literature. One analogy that I'm frequently hearing is the analogy with checklists for surgeons that can

Registration is open for my dataviz workshop at NYU. (link) This is a workshop in the sense of a creative writing workshop. Your "writing" are sketches of data visualization based on your selected datasets. In class, we critique all of...

Later this week, I'm off to Madrid to examine a PhD candidate at UNED (that's the Spanish Open University). This is interesting work on probabilistic network for health economic evaluation, so it should be good.As part of my trip, I'll also give a...

I still remember the first time I was asked to "consult" on a statistical problem. A former physics professor had some students who had gathered data that should lie along an arc of a theoretical circle. The professor asked if there was a regression technique that could find the center […] The post Fit a circle to data appeared first on The DO Loop.

Seasonality research is back! Well, at least a bit.I recall heady earlier days, with classic work like Granger's typical spectral shape, mutiplicative seasonal Box-Jenkins and the airline model, Nerlove's unobserved-components models and Harvey's basic...

Attention conservation notice: 2000+ words of academic navel-gazing about teaching a weird class in an obscure subject at an unrepresentative school; also, no doubt, more complacent than it ought to be. Once again, it's the brief period between submi...
