After listening to drumbeat of #War I was decided to share my vision on ongoing crisis of #Ukraine
Long thread
#Russia #Ukraine #WW3 #history Image
First that western audience is missing - that's a truth why #Ukraine? Russia was not invading in Ukraine in #2014 and do not annex a #Crimea

People of Crimea decided on the referendum to walk away from Ukraine and join #Russia on 16 of March 2014 Image
To understand why people of #Crimea and after them people of #Donbas and leave behind #Ukraine where is #coup happened
We filmed a very tough documentary on that topic, if you didn't see that - there is a free copy from us

Did you know that An Introduction to Statistical Learning (ISLR) book has an online course? 🎥 🌈❤️
@edXOnline is offering an online course by @Stanford University, following the book curriculum: 🧵 👇🏼

#rstats #Statistics #ML #datascience
The course instructors are two of the book authors - Prof. Trevor Hastie and Prof. @robtibshirani. While the book is based on #R some awesome people translate it to #python, #julialang, and other #Rstats flavors (see links on the comments below 👇🏼).
The course covers the following topics (aligned with the book curriculum):

(1)In dieser Grafik kann man gut erkennen, dass sich #Omikron unter den gleichen Umgebungs- und Immunitätsbedingungen in 🏴󠁧󠁢󠁥󠁮󠁧󠁿 mit einem 7x höherem #R-Wert ausbreitet.
(2) Dies bedeutet, dass Delta von einer Person auf eine weitere übertragen wird, während Omikron auf 7 weitere übertragen wird.

Man kann sagen, dass 🏴󠁧󠁢󠁥󠁮󠁧󠁿Delta recht gut im Griff hatte, jetzt kommt Omikron daher und stellt das marodierte NHS vor eine komplett neue Herausforderung
(3)In Flagge von Deutschland bremsen wir #Omikron durch die bestehenden Restriktionen um etwa ein Drittel (im Vergleich zu UK) aus. Da wir etwas später dran sind, haben wir auch mehr Zeit für die Entfaltung der Booster-Immunität.

🧵Ho letto con interesse il Suo articolo e mi colpiscono due passaggi.
1. L'affermazione che il #PatentBox (#PB) stia funzionando motivata dall'importo crescente e dal num. crescente dei beneficiari dell'agevolazione.
2. L'affermazione che l'agevolaz. abbia premiato i "migliori"
i.e. le aziende più "performanti" (migliori margini rispetto allo sfruttamento degli intangibili).
Poco più di un anno fa la #CortedeiConti ha (più che giustamente dal mio punto di vista) evidenziato 👇 come sia riduttivo misurare l'efficacia della misura basandosi meramente Image
sulle quantificazioni di cui al punto 1 ma sia invece necessario a) indagare su come l'agevolazione si sia distribuita tra diversi attori economici e b) analizzarne gli effetti in termini di crescita del numero di brevetti e addizionalità. Se quest'analisi, basata su micro-dati,

An interesting summary of an interview with Yukihiro Matsumoto, the creator of #Ruby programming language about ‘What’s a Perfect Programming Language ‘

🧵 A Thread for 🧵

#CodeNewbies #100DaysOfCode
(Yukihiro Matsumoto):

Language designers want to design the perfect language. They want to be able to say, "My language is perfect. It can do everything."

But it's just plain impossible to design a perfect language, Why ?
Because, there are two ways to look at a language.

One way is by looking at what can be done with that language.

The other is by looking at how we feel using that language—how we feel while programming.

I recently implemented some pairs trading strategies for a paper, and decided to share an implementation of the Gatev, Goetzmann & Rouwenhorst (2006) strategy on a short article on RPubs.…
#rstats #RPubs #DataScience #finance #pairstrading #reproducibility
In the RPubs post above, I provide the #R code to backtest the strategy, as well as some results replicating Gatev, Goetzmann & Rouwenhorst (2006) and Do and Faff (2010), and extending the sample to the end of 2020. In this thread, I show some of these results.
Pairs trading is a type of systematic trading strategy based on finding pairs of stocks or assets that have historically "moved together", and betting that divergences will eventually get corrected. It is a simple form of statistical arbitrage.

Infektionsgefahr in #Schulen über belastete #Aerosole
Professor #Kähler schließt sich der #AITAsk Bewertung an:
"#Lüften alleine reicht nicht. Die Schulen wurden ja lange zugemacht, weil es eben nicht reicht". #twlz #kmk #rki…
Schulen sind mittlerweile wieder geöffnet, weitere Jahrgänge sollen folgen, dabei steigen bundesweit die Infektionszahlen. Gleichzeitig breitet sich die Mutante #B117 weiter aus. #Schulen sollen "eher" keine Pandemie-Treiber und dank #AHA+L sicher sein, sagt das #RKI. Stimmt das?
Eine erste Warnung, was ein #Superspreader im #Klassenzimmer bewirken kann und warum #Schulen sehr schnell zu einem Pandemie-Treiber werden können, zeigte das Ergebnis der #AITask-#Modellierung bereits im August 2020: Superspreader Klassenzimmer #twlz #kmk

Logik zum #Öffnungsplan der #Bundesregierung
Wo, wie und wie schnell infiziert man sich mit dem #Coronavirus? Solange die Regierung Entscheidungen - magels Datenlage - ohne Evidenz trifft, solange ist es Willkür, wann welche Bereiche geöffnet und andere geschlossen bleiben #Spahn
Die Mutante #B117 erreicht in diesen Tagen -in den ersten Bundesländern- ihre #Dominanz. #R steigt zeitgleich und die #Regierung erhöht per #Öffnungsplan die #Mobilität: B117, Öffnungsplan u. gesteigerte Mobilität sind drei Faktoren die logisch #R exponentiell beeinflussen können
Zeitgleich werden #Kitas u. #Schulen geöffnet, also die Versammlungsorte, vor deren Öffnung uns Experten und Ärzte aus #Israel u. Kanada warnen. Begründet wird die #Öffnung mit "Meinungen" von Wissenschaftlern, deren #Studien -manipulierte Daten- aus #Schweden zitieren #twlz #KMK

We’re now passing over to @DrGWheeler to walk us through software for adaptive designs!
Sorry, attempt 2 (@JMSWason not too experienced with adding gifs!)
In 2020 Michael Grayling @UniofNewcastle & @DrGWheeler @ucl published a review of software for #AdaptiveDesigns in clinical trials.

Lack of available software is a known barrier to using better trial designs in practice. Q: “How bad is this problem?” 1/9…
Our research questions were:

1. How many articles proposing new adaptive designs included code with the paper, or a link to code available elsewhere?

2. Which adaptive design approaches and features are well supported by current software, and (importantly), which are not? 2/9

A note on reproducible GIS by economists: it's mostly absent. Here are some tips.
Reproducibility means that the inputs and methods can be repeated by a (somewhat) knowledgeable person. For GIS, that *might* (should) mean code, but it *definitely* means at least SOME instructions. Even if they are manual....
Maps are data. While your typical Stata/Matlab/R/Julia graph is data projected into Cartesian coordinates, maps are data projected into geographic coordinates. So at a minimum, we need to know what the inputs to the map are, same as we need to know inputs to graphs.

***Publication 101: Writing academic publication and it’s importance in scholarship applications***

I have received lot of messages from scholarship aspirants in the past days about publishing their academic article and thought I should share some tips. Let me start by saying
the feeling of not knowing how to start or even confident as you set out is normal, so you are not alone. As you may/may not know, the competition for scholarship spots is getting intense by the day and hence, the need to up your game to beat that competition (publications

will definitely make your application strong and also boost your writing/research profile). Now, let’s talk about how to submit a great article.

1. Start with a Draft: You need to put things down in writing. While it’s important to care about formatting here, you should
