Filter tuning risk: “63 days” & “60%” might be the winner of a big hidden search. Randomization after picking the best spec ≠ full data-mining control. #DataMining #MultipleTesting

Test 500 prompts and one will look legendary by pure luck.
Bailey & López de Prado calls it Probability of Backtest Overfitting (PBO).
Translation: your leaderboard is lying to you.

In short:
FDR → fixed linear prudence
sFDR → adaptive concave prudence
When data scales, prudence must scale too.

Kanako Fuyama and colleagues examine the impact on statistical power of correlations between outcomes in clinical trials with multiple primary outcomes, composite endpoints or prioritized outcomes. @HokkaidoUni @SCTorg #GPC #CompositeOutcomes #MultipleTesting #ClinicalTrials
This past month has seen the publication of a couple of new helpful papers providing further insights into the thorny issue of #MultipleTesting in trials 1/7

In #hydrological sciences at #EGU24, inflationary use of hypothesis tests with no adjustment for #multipletesting persists. Check out our 2020 paper for suitable adjustment methods in a #spatiotemporal setting: https://t.co/ArBuASJCwR @Ellis_Unit_Jena
@EffectDrost @governatorxyz @poapxyz @banklessDAO The hard way: state a hypothesis and define methods before the experiment begins to avoid p-hacking into disprovable POAP oblivion. #DeSci #MultipleTesting #Probability #deScientificMethod

Let's assume the correct penalty was applied to the alpha level at the final look after dose 3 to adjust for the fact they had already looked after dose 2.
I'm not sure how this is done though, so would be happy to hear from any clinical trial designers.
This week on #GenomicsBootCamp you can find a basic theoretical introduction to genome-wide association studies #GWAS

Another super amazing workshop with outstanding speakers organised by David Robertson of the @MRC_BSU!
Looking forward to it!

Advantages of Pair Testing
1. Incorporates Multiple Testing Perspectives
2. Makes way for a more in-depth Bug Investigation
3. Promotes Free Flow of Information by Breaking Down Silos...

@learningtotrd Onni ei välttämättä jatku, vaan voi tulla isojakin drawdowneja, mistä sitten taas ponnistetaan ylös. Yhtä kaikki, pelkällä sattumalla on iso rooli ja taidon erottaminen sattumasta on lyhyellä (itse asiassa pitkälläkin) aikavälillä hankalaa. #multipletesting
"[#MultipleTesting] is no problem if one focuses on a particular hypothesis..a priori.
..[decisions] can still be based on the..marginal p-value.
..problem only arises if one searches the list of p-values for significant results a posteriori.
..[this] is..common."
