10:02 AM | Logical foundations for mathematics? The first-order vs. second-order ‘dichotomy’? (Part IV of 'Axiomatizations of arithmetic...')
(It took me much longer than I had anticipated to get back to this paper, but here is the final part of my paper on axiomatizations of arithmetic and the first-order/second-order divide. Part I is here; Part II is here; Part III is here. As always, comments are welcome!)3. Logical foundations for mathematics? The first-order vs. second-order ‘dichotomy’?Given the (apparent) impossibility of tackling the descriptive and deductive projects at once with one and the same underlying […]

11:14 PM | Pre-processing for approximate Bayesian computation in image analysis
With Matt Moores and Kerrie Mengersen, from QUT, we wrote this short paper just in time for the MCMSki IV Special Issue of Statistics & Computing. And arXived it, as well. The global idea is to cut down on the cost of running an ABC experiment by removing the simulation of a humongous state-space vector, […]

10:45 PM | Homotopy Type Theory and Univalent Foundations I
In 2013, three dozens of today's brightest minds have just laid out new foundation of mathematics after a year of collective effort. This new paradigm better fits both informal and computationally-checkable mathematics. There is little doubt that it will fundamentally change our perspective on rigorous knowledge, and it could be that, in a few decades, the book they published turns out to be the bedrock of all mathematics, and, by extension, all human knowledge! Have a primer of this upcoming […]

6:27 PM | Teaching Bayesian applied statistics to graduate students in political science, sociology, public health, education, economics, . . .
One of the most satisfying experiences for an academic is when someone asks a question that you’ve already answered. This happened in the comments today. Daniel Gotthardt wrote: So for applied stat courses like for sociologists, political scientists, psychologists and maybe also for economics, what do we actually want to accomplish with our intro courses? […]The post Teaching Bayesian applied statistics to graduate students in political science, sociology, public health, education, […]

3:26 PM | Everyday Renaissance Astrology.
One of the joys of having run a moderately successful history of science blog for a number of years, and thus become somehow respectable, is that I occasionally get to review books; this is one of those reviews.  Regular readers … Continue reading →

Why it’s important to talk math with your children. “With practice, parents and children alike will find that math makes a very satisfying second language” On a related note, this The Atlantic article entitled “5 year olds can learn calculus” is going around and is worth reading. Can Bayesian statistics help find the missing Malaysian […]

1:28 PM | The candy weighing demonstration, or, the unwisdom of crowds
From 2008: The candy weighing demonstration, or, the unwisdom of crowds My favorite statistics demonstration is the one with the bag of candies. I’ve elaborated upon it since including it in the Teaching Statistics book and I thought these tips might be useful to some of you. Preparation Buy 100 candies of different sizes and […]The post The candy weighing demonstration, or, the unwisdom of crowds appeared first on Statistical Modeling, Causal Inference, and Social Science.

12:56 PM | Optimizing for Einstein and other homo-erotic theories
Jointly posted with Naked Capitalism. At 41, I’m a grown woman. I’ve had enough weird and bad experiences as a woman in the mathematics part of “STEM,” inside and outside of academia, that my skin is relatively thick, a fact I’m proud of. Most of the time I let stuff roll off of me. Even […]
