English social reformer, statistician and the founder of modern nursing Florence Nightingale was born in 1820.

Nightingale became famous for her work as a nurse during the Crimean War (1853–1856). Beyond her work in the Crimean War, Nightingale was a prolific writer and statistician. She used statistical methods to analyze and present data on healthcare and public health, making significant contributions to the field of medical statistics.

"Diagram of the causes of mortality in the army in the East" by Florence Nightingale. Example of polar area diagram by Florence Nightingale (1820–1910). This "Diagram of the causes of mortality in the army in the East" was published in Notes on Matters Affecting the Health, Efficiency, and Hospital Administration of the British Army and sent to Queen Victoria in 1858. This graphic indicates the annual rate of mortality per 1,000 in each month that occurred from preventable diseases (in blue), those that were the results of wounds (in red), and those due to other causes (in black). The legend reads: The Areas of the blue, red, & black wedges are each measured from the centre as the common vertex. The blue wedges measured from the centre of the circle represent area for area the deaths from Preventable or Mitigable Zymotic diseases, the red wedges measured from the centre the deaths from wounds, & the black wedges measured from the centre the deaths from all other causes. The black line across the red triangle in Nov. 1854 marks the boundary of the deaths from all other causes during the month. In October 1854, & April 1855, the black area coincides with the red, in January & February 1856, the blue coincides with the black. The entire areas may be compared by following the blue, the red, & the black lines enclosing them.

"Randomized trials cannot address all causal questions of importance in medicine and health policy and may have limited generalizability; thus, investigators may need to use observational studies as a source of evidence to address causal questions. The challenge, then, is to balance the importance of addressing the causal questions for which observational studies are needed with caution regarding the reliance on strong assumptions to support causal conclusions."

A challenge of our time truly

"Many of us out here doing applied science have to entirely self-teach and un-learn poor statistics and poor methods training."

So true.

I see recent graduates with the same faulty NHST-based statistical education that I received decades ago. It's disappointing how poorly education has kept up with new and better statistical methods.

In #QuantumFieldTheory, scattering amplitudes can be computed as sums of (very many) #FeynmanIntegral s. They contribute differently much, with most integrals contributing near the average (scaled to 1.0 in the plots), but a "long tail" of integrals that are larger by a significant factor.
We looked at patterns in these distributions, and one particularly striking one is that if instead of the Feynman integral P itself, you consider 1 divided by root of P, the distribution is almost Gaussian! To my knowledge, this is the first time anything like this has been observed. We only looked at one quantum field theory, the "phi^4 theory in 4 dimensions". It would be interesting to see if this is coincidence for this particular theory and class of Feynman integrals, or if it persists universally.

Here's the logical structure of what you will be taught in terms of as a masters student in pretty much any field.

If MY DATA is a sample from two random number generators of PARTICULAR TYPE, and MY TEST has a small p value then MY FAVORITE EXPLANATION FOR THE DIFFERENCES IS TRUE.

This is, quite simply, a logical fallacy. The first thing wrong is that your data IS NOT a sample from a random number generator of that particular type. So we can ignore the rest logically.

Today I am writing on the AIC functions available in my hashtag#R hashtag#Package TidyDensity.

There are many of them, with many more on the way. Some of them are a little temperamental but not to worry it will all be addressed.

My approach is different then that of fitdistrplus which is an amazing package. I am trying to forgo the necessity of supplying a start list where it may at times be required.

Want a simple form of #MCMC analysis in #R well, I got you covered.

My #R #Package TidyDensity has a function called tidy_mcmc_sampling() that is pretty straight forward. It takes a raw vector and performs the calculation you give it over a default of 2k samples.

I hope you find it useful.

The plotting, statistical, and data selection tools in the mapdata.py data explorer (https://pypi.org/project/mapdata/) can be used even if you don't have any map data. Just add dummy latitude and longitude values to the data table. Zeroes will do. The map and the dummy columns can both be hidden, and you can then explore the data table with the other available tools.

Taka obserwacja kulturowo-socjologiczna: na Fediverse od dawna jest trochę Rosjan “z Rosji” (w sensie, że nie emigrantów), głównie uciekinierów z mainstreamowych rosyjskich sieci społecznościowych typu VK po wprowadzeniu cenzury kilka lat temu. Poza grupą autentycznie szurniętych nacjonalistów (którzy też byli wtedy w Rosji ścigani, stąd ucieczka z VK) z większością z nich do wojny i przez pierwszy rok można było normalnie dyskutować. Mam tu na myśli dyskusję na poziomie jaki mogą prowadzić ludzie mający czasem odmienne poglądy ale potrafiący wysłuchać argumentów drugiej strony i z nimi polemizować lub je przyjąć. Ale w ciągu ostatniego roku dokonała się ciekawa zmiana kulturowa. Jeżeli mogę dokonać kilku uogólnień na podstawie niedawnej (i chyba ostatniej) dyskusji z nimi:

  • W złym tonie jest podawanie… źródeł informacji. W dobrym tonie jest pisanie “swoimi słowami”. To znaczy, jeżeli ktoś napisze “ja wiem, że rakiety S-300 nie mogą trafiać w cele naziemne” to ma to z ich punktu widzenia większą wartość poznawczą niż ”nawet ze źródeł rosyjskich wynika, że mogą - tutaj jest link do TopWar.ru” (popularny portal wojskowy w Rosji). Nie mam pojęcia z czego to wynika, podejrzewam jakiś podprogowy komunikat o tym, że wszystkie linki mogą prowadzić do exploitów i wirusów.
  • Całkowite pogrążenie w oficjalnej rosyjskiej narracji - oni nie wiedzą, że Charków był regularnie ostrzeliwany od lutego 2022 i autentycznie myślą, że rosyjskie ostrzały Charkowa zaczęły się dopiero w odwecie za ukraińskie ostrzały Biełgorodu czyli około grudnia 2023.
  • Całkowita brak zdolności do konfrontacji z informacją nie pasującą do tej oficjalnej narracji. W naszej kulturze, jeżeli ktoś poda informację sprzeczną z naszą wiedzą to zaczyna się kopanie w źródłach - albo ja mam błędne źródło, albo on/ona i na podstawie uznawanych przez obie strony można to ustalić. Rosyjskie “pokolenie wojenne” po prostu kończy dyskusję, nie było tematu.
  • Ciekawe zjawisko “podwójnej moralności” - wobec “swoich” przyznajemy nieco więcej (np. ludobójcze cele Kremla w zakresie “złamania Ukrainy”) niż wobec “obcych” (negowanie tych wypowiedzi i upieranie się, że to tylko “”emocje”). Ale to akurat Rosjanie mieli zawsze, to nie jest nowe zjawisko.
  • Odrzucanie dowolnych relacji świadków czy wręcz materiałów wideo z miejsc wydarzeń na tej podstawie, że “nie było cię tam na miejscu, nie wiesz jak było”. W konsekwencji tuzin bezpośrednich relacji wideo z danego miejsca jest odrzucany jako “niewiarygodny” ale obwieszczenia oficjalnych przedstawicieli władzy jest traktowane przynajmniej jako wyraz oficjalnej wersji.
  • Bezkrytyczne podejście do częstych w rosyjskiej oficjalnej narracji zmian stanowiska o 180°. Fakt, że dzisiaj władza mówi coś całkowicie odwrotnego niż wczoraj nie wywołuje absolutnie żadnych refleksji na temat tego, że władza może w danym przypadku kłamać oraz, że jutro powie coś inne niż dzisiaj. Jest prawda życia, i jest “prawda etapu”.

W większości są to zjawiska dość oczywiste dla każdego kto ma kontakt z Rosjanami “z Rosji”, nowością dla mnie była obsesyjna fiksacja na “swoimi słowami” oraz odrzucanie źródeł. Nie wiem w jaką stronę to idzie ale wygląda na to, że oni sami siebie zagnali w jakąś sekciarską informacyjną czarną dziurę. Długofalowe konsekwencje, przede wszystkim dla rosyjskiego społeczeństwa, będą dramatyczne.

May I add some hashtags in order to solicit views of psychologists and others who deal with human (or animal) cognitive modelling of reality? I would be fascinated to read about the degree to which we're all vulnerable to bias, the highest-yield methods of protecting oneself from bias (especially in social media), and of helping reflect back to others their own views in a way that lets them critique them. I think the last point is especially hard, especially if the other person has no desire for critical thinking (and as humans, we are terrible at critical thinking!).

If there are any textbooks on the subject, ideally written by scientists &/or aimed at scientists, I'd be keen as mustard to know about them!

If anyone has opinions on the work of Han, Lee, Wang, & Baldwin (librai fact checking automation - https://github.com/Libr-AI/OpenFactVerification ) I'd be all ears too.

Please feel free to boost this if you think answers might interest you.
