Attention conservation notice: Navel-gazing about teaching. Well, that was exhausting. Everything seemed to take me at least as much effort and time as the year before, despite recycling a lot of material. There continues to not be enough manpower ...

It's that time of year again: 36-350, Statistical Computing Description: Computational data analysis is an essential part of modern statistics. Competent statisticians must not just be able to run existing programs, but to understand the principles ...

Introduction to the course: statistical programming for autonomy, honesty, and clarity of thought. The functional programming idea: write code by building functions to transform input data into desired outputs. Basic data types: Booleans, integers, ...

In which we play around with basic data structures and convince ourself that the laws of probability are, in fact, right. (Or perhaps that R's random number generator is pretty good.) Lab Introduction to Statistical Computing

In which we practice working with data frames, grapple with some of the subtleties of R's system of data types, and calculate the consequences of doodling while bored in lecture. Assignment, due at 11:59 pm on Thursday, 5 September 2013 Introductio...

Lecture 3: Conditioning the calculation on the data: if; what is truth?; Boolean operators again; switch. Iteration to repeat similar calculations: for and iterating over a vector; while and conditional iteration (reducing for to while); repeat and u...

Gelman responds to the comment[i] I made on my 8/31/13 post: Popper and Jaynes Posted by Andrew on 3 September 2013 Deborah Mayo quotes me as saying, “Popper has argued (convincingly, in my opinion) that scientific inference is not inductive but deductive.” She then follows up with: Gelman employs significance test-type reasoning to reject a model when the data sufficiently disagree. […]

Deborah Mayo quotes me as saying, “Popper has argued (convincingly, in my opinion) that scientific inference is not inductive but deductive.” She then follows up with: Gelman employs significance test-type reasoning to reject a model when the data sufficiently disagree. Now, strictly speaking, a model falsification, even to inferring something as weak as “the model […]The post Popper and Jaynes appeared first on Statistical Modeling, Causal Inference, and Social Science.

Like piranha fish in a feeding frenzy, different research tribes fight furiously to stake claims in new areas like financial engineering and risk management. Fringe players, in particular, often strive to move toward the center, or to redefine the cent...

Following up on my entry the other day on post-publication peer review, Dan Kahan writes: You give me credit, I think, for merely participating in what I think is a systemic effect in the practice of empirical inquiry that conduces to quality control & hence the advance of knowledge by such means (likely the title […]The post Evaluating evidence from published research appeared first on Statistical Modeling, Causal Inference, and…

The current issue of Significance includes an article by me on the "pending marriage between statistics and Big Data". If you are a member of either the American Statistical Association or the Royal Statistical Society, you should be able to access the article via this link. If you don't belong to one of those, and you have a smartphone or tablet, you can download the Significance app -- because 2013…

Thanks to Rikky Vohra for bringing still more to my attention. Absolutely classic!

While at the Joint Statistical Meeting a few weeks ago I was talking to a friend about various aspects to clinical trials. He indicated that no current R package was able to perfectly reproduce Passing-Bablok (PB) regression so that it exactly matched SAS. He ultimately wrote a couple of functions and kindly shared them with […]
