#statstab #487 More than meets the ITT: A guide for anticipating and investigating nonsignificant results in survey experiments
Thoughts: I see a lot of papers that make at least one of the 7 errors for "no effect".

#statstab #468 Confidence Distribution, the Frequentist Distribution Estimator of a Parameter: A Review
Thoughts: Frequentist stats must move beyond point and interval estimators, and adopt "distribution estimators".

#statstab #463 One-and-a-half sided test
Thoughts: Alberson has a more different take on the issues from #461 and #462: human behaviour.

#statstab #462 The paradox of one-sided vs. two-sided tests of significance
Thoughts: A solution to Royall's paradox from #461. The "null" is not one thing.

#statstab #461 The One-Sided P-Value Paradox
Thoughts: "I have concluded the stronger proposition, probability of heads > ½, but I cannot conclude the weaker proposition, probability of heads > ½ or < ½"

#statstab #458 There is still only one test
Thoughts: Downey make a good point that all/any testing ensemble does essentially the same thing.

#statstab #413 Counternull Sets in Randomized Experiments
Thoughts: The counternull is a lost statistic, that is woefully underused when teaching stats.

#statstab #364 Distribution of Cohen's d, p-values, and power curves for an independent two-tailed t-test
Thoughts: Useful for explaining why we use 5% alpha and what power does to p-values.

#statstab #361 Vovk-Sellke Maximum p-Ratio (VS-MPR)
Thoughts: Can p-values provide evidence for H1 over H0? YES!*
(*if you make some assumptions and go a smidgen Bayesian)
VS-MPR is reported in @JASPStats

On this day, the brilliant statistician responsible for many tools we still use now (ANOVA,MLE,Exact Tests, etc.) but most importantly for popularizing significance & p-values, was born. Sir Ronald Aylmer Fisher FRS (17 Feb 1890 – 29 Jul 1962). #statsky #datascience #statistics #pvalue #significance

Statisticians are like magicians—
They make the data disappear... and then pull a p-value out of a hat. 🧙♂️✨
But sometimes, the magic’s just a coincidence! 😂📊
