4:00 AM | Peirce’s 1870 “Logic Of Relatives” • Comment 10.10
The last of the three examples involving the composition of triadic relatives with dyadic relatives is shown again in Figure 25. (25) The hypergraph picture of the abstract composition is given in Figure 26. (26) This example illustrates the way that Peirce … Continue reading →

1:30 PM | Peirce’s 1870 “Logic Of Relatives” • Comment 10.9
The use of the concepts of identity and teridentity is not to identify a thing-in-itself with itself, much less twice or thrice over — there is no need and therefore no utility in that. I can imagine Peirce asking, on Kantian … Continue reading →

9:30 PM | Peirce’s 1870 “Logic Of Relatives” • Comment 10.8
There’s a critical transition point that we find in sight of Peirce’s 1870 Logic of Relatives and it’s a point that turns on the teridentity relation. In taking up the next example of relational composition, let’s substitute the relation for … Continue reading →
3:22 AM | Phil 6334: Foundations of statistics and its consequences: Day #12
We interspersed key issues from the reading for this session (from Howson and Urbach) with portions of my presentation at the Boston Colloquium (Feb, 2014): Revisiting the Foundations of Statistics in the Era of Big Data: Scaling Up to Meet the Challenge. (Slides below)*. Someone sent us a recording  (mp3)of the open-ended panel discussion from that Colloquium including: Mayo, Xiao-Li Meng (Harvard), Kent Staley […]

5:09 PM | Shakespeart, religion and mathematics
I recently considered the role that mathematics plays in bringing meaning, or perhaps even story, to our experience. Mathematics is often used to reveal the structure that can be found in large sets of data, or in any number of physical things that change over time,  or in the properties of the abstractions themselves.  Mathematics, [...]

2:42 AM | Getting Credit (or blame) for Something You Didn’t Do (BP oil spill)
  Four years ago, many of us were glued to the “spill cam” showing, in real time, the gushing oil from the April 20, 2010 explosion sinking the Deepwater Horizon oil rig in the Gulf of Mexico, killing 11, and spewing oil until July 15.(Remember junk shots, top kill, blowout preventers?)[1] The EPA has lifted its gulf drilling ban on BP just […]

10:00 PM | Peirce’s 1870 “Logic Of Relatives” • Comment 10.7
Here is what I get when I analyze Peirce’s “giver of a horse to a lover of a woman” example along the same lines as the dyadic compositions. We may begin with the mark-up shown in Figure 19. (19) If we … Continue reading →

Tanya Khovanova filled us in on what she learned from John Conway: http://blog.tanyakhovanova.com/?p=489 3) Just in case you've been
1:54 AM | Duality: Confidence intervals and the severity of tests
A question came up in our seminar today about how to understand the duality between a simple one-sided test and a lower limit (LL) of a corresponding 1-sided confidence interval estimate. This is also a good route to SEV (i.e., severity). Here’s a quick answer: Consider our favorite test of the mean of a Normal distribution with […]

7:30 PM | Peirce’s 1870 “Logic Of Relatives” • Comment 10.6
As Peirce observes, it is not possible to work with relations in general without eventually abandoning all of one’s algebraic principles, in due time the associative law and maybe even the distributive law, just as we have already given up … Continue reading →

A Statistical Model as a Chance Mechanism Aris Spanos  Jerzy Neyman (April 16, 1894 – August 5, 1981), was a Polish/American statistician[i] who spent most of his professional career at the University of California, Berkeley. Neyman is best known in statistics for his pioneering contributions in framing the Neyman-Pearson (N-P) optimal theory of hypothesis testing […]

“There was a vain and ambitious hospital director.

11:30 AM | Week's Additional Links
Some additional links to pass along, that I didn't already mention in blogposts this week:1) just yesterday Sol Lederman linked to this recent Math StackExchange page of "Visually stunning math concepts which are easy to explain" -- that says it all:http://tinyurl.com/pkxjzax(nice examples and variety)2) Long, interesting 1999 piece from Alfie Kohn (pointed out by "Matthew Maddux" this week)
9:24 AM | CfP: Agent-Based Modeling in Philosophy
LMU Munich11-13 December 2014www.lmu.de/abmp2014In the past two decades, agent-based models (ABMs) have become ubiquitous in philosophy and various sciences.  ABMs have been applied, for example, to study the evolution of norms and language, to understand migration patterns of past civilizations, to investigate how population levels change in ecosystems over time, and more.  In contrast with classical economic models or population-level models in biology, ABMs are praised for their […]

3:13 PM | More Thoughts on Constructing the World (David Chalmers)
With permission, I'm posting some of David Chalmers' quick thoughts/responses to Panu Raatikainen's critical notice of David's recent aufbauesque (2012) book, Constructing the World (some lectures on this are here on youtube):---------------------(1) Are bridge laws allowed in the scrutability base, and if so does this trivialize scrutability theses? Bridge laws are certainly not disallowed from the base in general (indeed, I'd have psychophysical bridge laws in my own base). When I said that […]

This is the third in a series of three posts in which I rehearse what I hope to say at the Author Meets Critics session for Lara Buchak's tremendous new book Risk and Rationality at the Pacific APA in a couple of weeks.  The previous two posts are here and here.  In the first post, I gave an overview of risk-weighted expected utility theory, Buchak's alternative to expected utility theory.  In the second post, I gave a prima facie reason for worrying about any departure from […]

We have sufficiently covered the application of the comma functor to absolute terms, so let us return to where we were in working our way through CP 3.73 and see whether we can validate Peirce’s statements about the commafications of dyadic … Continue reading →
11:45 AM | Keith Devlin Explains MY Past (maybe)
The debate over what content to teach in math and how to teach it seems to go on forever (as did the first draft of this post!)…. First off, I'll mention that Richard Feynman famously had his own outspoken views on science school textbooks, which he covered in a chapter of one of his books, reprinted here: http://www.textbookleague.org/103feyn.htm It's a long (but entertaining) read so I'd

It was from my Virginia Tech colleague I.J. Good (in statistics), who died five years ago (April 5, 2009), at 93, that I learned most of what I call “howlers” on this blog. His favorites were based on the “paradoxes” of stopping rules. (I had posted this last year here.) “In conversation I have emphasized to other statisticians, […]
