Introducing shinyStan

As a project for Andrew’s Statistical Communication and Graphics graduate course at Columbia, a few of us (Michael Andreae, Yuanjun Gao, Dongying Song, and I) had the goal of giving RStan’s print and plot functions a makeover. We ended up getting a bit carried away and instead we designed a graphical user interface for interactively exploring virtually […] The post Introducing shinyStan appeared first on Statistical Modeling, Causal Inference, and Social Science.

Rembrandt van Rijn (2) vs. Bertrand Russell

For yesterday, the most perceptive comment came from Slugger: Rabbit Angstrom is a perfect example of the life that the Buddha warns against. He is a creature of animal passions who never gains any enlightenment. In any case, I think we can all agree that Buddha is a far more interesting person than Updike. But, […] The post Rembrandt van Rijn (2) vs. Bertrand Russell appeared first on Statistical Modeling,…

Reflecting on Alamar’s reflection on sports data

March 2, 2015
By

Ben Alamar reflects on the rise of data analytics in the NBA (link). I like this passage very much, which really nails home the point that good analytics requires intuition: The hours of waiting [during draft meetings] were often filled with watching film of prospects. It helped me refine my analysis, as I soaked up details from scouts that I never would have seen on my own. ("Rewind that. ...…

What hypothesis testing is all about.  (Hint:  It’s not what you think.)

I’ve said it before but it’s worth saying again. The conventional view: Hyp testing is all about rejection. The idea is that if you reject the null hyp at the 5% level, you have a win, you have learned that a certain null model is false and science has progressed, either in the glamorous “scientific […] The post What hypothesis testing is all about.

In this four week course we will teach statistical techniques that are commonly used in the analysis of high-throughput data and their corresponding R implementations. In Week 1 we will explain inference in the context of high-throughput data and introduce the concept of error controlling procedures. We will describe the strengths and weakness of the Bonferroni correction,

Avoid loops, avoid the APPLY function, vectorize!

What I discovered is a good reminder about the importance of vectorizing user-defined modules. The program in this blog […] The post Avoid loops, avoid the APPLY function, vectorize! appeared first on The DO Loop.

Modeling Earthquake Dynamics

In 2012, with Marilou Durand, student at UQAM, we have been working on the seismic gap hypothesis, see e.g. McCann et al. (1978) or Kagan & Jackson (1991), or to be more specific, on the dynamics between earthquakes magnitude (or seismic moment) and inter-occurence durations. Our paper should appear soon in the Journal of Seismology, In this paper, we investigate questions arising in Parsons & Geist (2012). Pseudo causal models connecting magnitudes…

To Beware or To Embrace The Prior

In this guest post, Jeff Rouder reacts to two recent comments skeptical of Bayesian statistics, and describes the importance of the prior in Bayesian statistics. In short: the prior gives a Bayesian model the power to predict data, and prediction is what allows the evaluation of evidence. Far from being a liability, Bayesian priors are what make Bayesian statistics useful to science.Jeff Rouder writes:Bayes' Theorem is about 250 years old. For…

Buddha (3) vs. John Updike

Yesterday‘s winner is Friedrich Nietzsche. I don’t really have much to say here: there was lots of enthusiasm about the philosopher and none at all for the cozy comedian. Maybe Jonathan Miller would’ve been a better choice. Now for today’s battle. Buddha is seeded #3 among founders of religions.
