Jerzy Neyman and “Les Miserables Citations” (statistical theater in honor of his birthday)

For my final Jerzy Neyman item, here’s the post I wrote for his birthday last year:  A local acting group is putting on a short theater production based on a screenplay I wrote:  “Les Miserables Citations” (“Those Miserable Quotes”) [1]. The “miserable” citations are those everyone loves to cite, from their early joint 1933 paper: We are inclined to think that as […]

Neyman: Distinguishing tests of statistical hypotheses and tests of significance might have been a lapse of someone’s pen

Neyman: Distinguishing tests of statistical hypotheses and tests of significance might have been a lapse of someone’s pen

I’ll continue to post Neyman-related items this week in honor of his birthday. This isn’t the only paper in which Neyman makes it clear he denies a distinction between a test of  statistical hypotheses and significance tests. He and E. Pearson also discredit the myth that the former is only allowed to report pre-data, fixed error probabilities, and are […]

If you’re seeing limb-sawing in P-value logic, you’re sawing off the limbs of reductio arguments

If you’re seeing limb-sawing in P-value logic, you’re sawing off the limbs of reductio arguments

I was just reading a paper by Martin and Liu (2014) in which they allude to the “questionable logic of proving H0 false by using a calculation that assumes it is true”(p. 1704).  They say they seek to define a notion of “plausibility” that “fits the way practitioners use and interpret p-values: a small p-value means […]

Er, about those other approaches, hold off until a balanced appraisal is in

Er, about those other approaches, hold off until a balanced appraisal is in

I could have told them that the degree of accordance enabling the ASA’s “6 principles” on p-values was unlikely to be replicated when it came to most of the “other approaches” with which some would supplement or replace significance tests– notably Bayesian updating, Bayes factors, or likelihood ratios (confidence intervals are dual to hypotheses tests). [My commentary […]

The ASA Document on P-Values: One Year On

I’m surprised it’s a year already since posting my published comments on the ASA Document on P-Values. Since then, there have been a slew of papers rehearsing the well-worn fallacies of tests (a tad bit more than the usual rate). Doubtless, the P-value Pow Wow raised people’s consciousnesses. I’m interested in hearing reader reactions/experiences in connection with […]

3 YEARS AGO (FEBRUARY 2014): MEMORY LANE

MONTHLY MEMORY LANE: 3 years ago: February 2014. I normally mark in red three posts from each month that seem most apt for general background on key issues in this blog, but I decided just to list these as they are (some are from a seminar I taught with Aris Spanos 3 years ago; several on Fisher were recently reblogged). I […]

Guest Blog: STEPHEN SENN: ‘Fisher’s alternative to the alternative’

As part of the week of recognizing R.A.Fisher (February 17, 1890 – July 29, 1962), I reblog a guest post by Stephen Senn from 2012.  (I will comment in the comments.) ‘Fisher’s alternative to the alternative’ By: Stephen Senn [2012 marked] the 50th anniversary of RA Fisher’s death. It is a good excuse, I think, to […]

Guest Blog: ARIS SPANOS: The Enduring Legacy of R. A. Fisher

By Aris Spanos One of R. A. Fisher’s (17 February 1890 — 29 July 1962) most re­markable, but least recognized, achievement was to initiate the recast­ing of statistical induction. Fisher (1922) pioneered modern frequentist statistics as a model-based approach to statistical induction anchored on the notion of a statistical model, formalized by: Mθ(x)={f(x;θ); θ∈Θ}; x∈Rn […]
