Kind reminder that "validated" generally means "someone looked at it" not "someone looked at it and judged it to be good and useful"

#AddAStatisticalWordorPhraseRuinAMovie In the spirit of Jimmy Fallon, add a statistical word or phrase to a movie title and change its meaning. I'm putting together a top ten list of these for the @TheASAPodcast and would love to add yours to the list. Here are some examples:

With COVID, and all infections: Symptoms occur for at least 2 VERY different reasons 1) Immunity Fighting the infection (fever, congestion) 2) The infection winning & causing harm (lose smell, breathing issues) Symptoms do NOT define if you are infectious, the virus does! 1/

@mattansb @statsepi @MaartenvSmeden I don’t know why but I read this like the Pokémon game meme: Covariate used Noise. It had no effect.

Fantastic work and congratulations to @vickyedwards14 for pulling together this tough dual submission from @OPRG_UniChi monitoring officer training! Fun figure: disparity in CHO/PRO intake timing between when training could allow core meals (a, d) vs. field exercise (b, e)

@TenanATC @ExPhysStudent Thanks- This is precisely the sort of thing that prompted my question. Seeing one-to-one time-aligned data from an individual, and wanting to know if/what approaches exist to statistically do the “visual checking”. Like “pattern/shape” agreement - if that makes sense!

Will be completely out of my depth- but what approaches exist for equivalence/agreement across high frequency time-series data? (E.g time-aligned HRV in 2 devices). Many claim “correlation” by superimposing one longitudinal pattern on top of another. Ideas? (Perhaps @TenanATC?)

@ExPhysStudent @TenanATC Aaron, thanks for saying this - I would be interested whether there are some who would not define this as agreement - or it’s close enough (not wordplay intended). I suppose it may also depend on what each epochs of time you repeatedly apply this over.

@TenanATC @ExPhysStudent I think this was one of my concerns - was whether average differences over time could be used for “sameness” - the methods above are helpful. I will look forward to trying these all out on day!

@ExPhysStudent @TenanATC Glad you’ve joined the party too Aaron! Aware that agreement and equivalence are different, as LoA and equiv testing are sometimes used in tandem to show different concepts, so this was an either/or type question to see what methods existed!

@TenanATC Thanks Matt - I figured you might have! I am not (currently) looking to run an analysis, but I will have use in the near future. But have just been seeing a lot of claims without an analysis of this type- so it made me wonder what existed and/or is actually appropriate.

It remains surprising to me that a limited analysis, that told us little we didn't already know, not only made the front page of the NYT, but seems to have been taken as "case-closed" on non-lab origins of sars-2.

There is no scientific merit to the use of a simplified heatmap (kernel density estimate) to represent residential addresses of early COVID cases in Worobey et al (2022) zenodo.org/record/6299600. @MichaelWorobey @acritschristoph @K_G_Andersen @stuartjdneil @edwardcholmes @arambaut

JUST IN: a new DNA sequence, known as TLDR, has been identified. It is so long that the polymerase becomes bored and stops transcribing it.
