The Poisson distribution is just a limiting case of the binomial distribution and not needed to explain any of the concepts that drive statistical inference, so its absence from an introductory text is hardly something to fuss about.

While All of Statistics is wonderful in its genre, it really isn't a good place to start to learn statistics. Firstly because it focuses very heavily on the theory and contains very little on practical modeling. Secondly because the th

It is perfectly possible to affirm that a company has the legal right to do whatever they wish, while at the same time arguing that you find it disgraceful. Specifically with regards to Facebook, they position themselves as a platform and n

Yep, there's a link with regularization and also with informative priors – James-Stein works so well because across an incredibly wide range of scenarios, a parameter estimate of infinity is not nearly as likely as a parameter estimate

This is a false dichotomy. I would prefer a world in which Banzi worked together with Barragán, which Barragán would have clearly loved and which might have given Arduino an innovator at its helm and the ability to actually keep up with the

And this proves your point that information should not be owned how? You're making various factual statements about what is easy, what is hard, what societies tend to condemn and tend not to condemn, but nowhere in there is a line of r

That's a bit of an arbitrary distinction. Without the government monopoly on violence, what's to stop me from knocking your door down and forcing you to perform free labor for me? Do you think ownership is part of the natural univ

At least here in Belgium, project proposals (which are indeed required) can come from either the student or a principal investigator. Many of the most talented students pick their own topic, and the topic is accepted or rejected by an indep

Oxford also puts PhD students on a pretty strict timeline. I don't think an Oxford PhD is a joke.

You do realize that what you're proposing is in no way supported by science but is merely your personal theory based on an analogy, right?

I studied the Hernan/Robins book for a course on causal inference, and I love it. But frankly it's a pretty niche topic, and so for the non-statisticians here on HN who are trying to get better at statistics, just keep in mind tha

They're different questions to some extent. In the statistical literature on causality, the counterfactual definition is almost universally accepted: if you do X then Y happens, but if you wouldn't have done X, Y wouldn't hav

Good catch. Outcome (or error, which boils down to the same thing) can't just be anything either, though, e.g. a common pattern is that the variance in an outcome increases when the predictor increases (e.g. a machine behaves more erra

You're right, there is lots of confusion in the topic and not all texts on regression get it right. Theoretically, linear regression depends only on a normally distributed outcome variable, the predictors don't have to be normally

AIC depends on residual variation just like R^2, so I guess some people might be inclined to call it AIC_R to make that clear. Also, it's Mallows' C_p :-)

Yep, there is really no other book like Harrell. There's a 2015 edition with some good improvements too. Definitely not an introduction, though – it assumes you already know how regression works and preferably have already used it quit
