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

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 โ 29 Jul 1962). #statsky #datascience #statistics #pvalue #significance

The fallacy of p values..a significant part of our research uses p value..but with very little knowledge of how to interpret it

Best moment in the video:
"I'm not gonna define p-values today, forgive me."
Maybe James should.
Not that there aren't any good definitions (e.g. check www.ncbi.nlm.nih.gov/pmc/articles...).
But presented by James, at least coffee drinkers might understand it better!
