Excursion 1 Tour II (4th stop): The Law of Likelihood and Error Statistics (1.4)

Ship Statinfasst

We are starting on Tour II of Excursion 1 (4th stop).  The 3rd stop is in an earlier blog post. As I promised, this cruise of SIST is leisurely. I have not yet shared new reflections in the comments–but I will!

Panel Discussion Questions from my Neyman Lecture: “Severity as a basic concept in philosophy of statistics”

 

Giordano, Snow, Yu, Stark, Recht

My Neyman Seminar in the Statistics Department at Berkeley was followed by a lively panel discussion including 4 Berkeley faculty, orchestrated by Ryan Giordano (Dept of Statistics):

  • Xueyin Snow Zhang (Dept. of Philosophy)
  • Bin Yu (Depts. of Statistics, Electrical Engineering and Computer Sciences)
  • Philip Stark (Dept. of Statistics)
  • Ben Recht (Dept. of Electrical Engineering and Computer Sciences)

Response to Ben Recht’s post (“What is Statistics’ Purpose?”) on my Neyman seminar (ii)

.

There was a very valuable panel discussion after my October 9 Neyman Seminar in the Statistics Department at UC Berkeley.  I want to respond to many of the questions put forward by the participants (Ben Recht, Philip Stark, Bin Yu, Snow Zhang)  that we did not address during that panel. Slides from my presentation, “Severity as a basic concept of philosophy of statistics” are at the end of this post (but with none of the animations). I begin in this post by responding to Ben Recht, a professor of Artificial Intelligence and Computer Science at Berkeley, and his recent blogpost, What is Statistics’ Purpose? On severe testing, regulation, and butter passing, on my talk. I will consider: (1) A complex or leading question; (2) Why I chose to focus about Neyman’s philosophy of statistics and (3) What the “100 years of fighting and browbeating” were/are all about.

Excursion 1 Tour I (3rd stop): The Current State of Play in Statistical Foundations: A View From a Hot-Air Balloon (1.3)

Third Stop

Readers: With this third stop we’ve covered Tour 1 of Excursion 1.  My slides from the first LSE meeting in 2020 which dealt with elements of Excursion 1 can be found at the end of this post. There’s also a video giving an overall intro to SIST, Excursion 1. It’s noteworthy to consider just how much things seem to have changed in just the past few years. Or have they? What would the view from the hot-air balloon look like now?  I will try to address this in the comments.

Excursion 1 Tour I (2nd Stop): Probabilism, Performance, and Probativeness (1.2)

.

Readers: I gave the Neyman Seminar at Berkeley last Wednesday, October 9, and had been so busy preparing it that I did not update my leisurely cruise for October. This is the second stop. I will shortly post remarks on the the panel discussion that followed my Neyman talk (with panelists, Ben Recht, Philip Stark, Bin Yu, and Snow Zhang), which was quite illuminating. 

“I shall be concerned with the foundations of the subject. But in case it should be thought that this means I am not here strongly concerned with practical applications, let me say right away that confusion about the foundations of the subject is responsible, in my opinion, for much of the misuse of the statistics that one meets in fields of application such as medicine, psychology, sociology, economics, and so forth”. (George Barnard 1985, p. 2)
