I wonder how easy it is, to do simple statistics with Python and R. For example, to calculate mean, median and other summary statistics. Let’s start with the following very simple data set. height weight 1.85 85.0 1.80 79.1 1.91 80.5 1.75 80.3 1.77 […]

Bayes and null hypothesis significance testing
I found these interesting articles about Bayes and null hypothesis significance testing by Andrew Gelman. What’s wrong with Bayes My problem is not just with the methods – although I do have problems with the method – but also with the ideology. https://statmodeling.stat.columbia.edu/2019/12/03/whats-wrong-with-bayes/ Copyright […]
Troubled p-Values
It’s not just p=0.048 vs. p=0.052 https://statmodeling.stat.columbia.edu/2019/09/06/__trashed-2/ If nobody likes p-values, why are we still using it?
Statistik Heute
Zwei interessante Artikel zur Statistik. Die Statistik erfindet sich neu “Strichlisten und Fragebögen sind von gestern. Statistiker setzen zunehmend auf Satelliten, Sensoren und soziale Medien. Auf dem Spiel steht die öffentliche Wahrheit.” https://www.sueddeutsche.de/wissen/datenwissenschaft-die-statistik-erfindet-sich-neu-1.4377781 Copyright © Süddeutsche Zeitung Digitale Medien GmbH / Süddeutsche Zeitung GmbH […]
Ordnung in den Primzahlen
https://www.deutschlandfunk.de/mathematik-forscher-entdecken-ueberraschend-eine-ordnung-in.2850.de.html?drn:news_id=927709 Interessant. Aber was bedeutet das jetzt? Das Verschlüsselung nicht mehr sicher ist?
Quantum-Andersartigkeit
“Ein mathematisches Resultat zeigt: Selbst ein unendlich schneller klassischer Computer kann dem Quantenrechner nicht das Wasser reichen.” https://www.spektrum.de/news/quantencomputer-sind-grundsaetzlich-anders/1574062 Wann kann man die Dinger endlich kaufen?

The Maths of Randomness
Martin Hairer writes for Plus Magazine about probability, Bayesians and frequentists. The maths of randomness https://plus.maths.org/content/maths-randomness I really like the section about Bayesians vs frequentists. I wish there was more on this topic.
Mathematics of Black Holes
Kevin Hartnett writes for Quanta Magazine about black holes. Mathematicians Disprove Conjecture Made to Save Black Holes https://www.quantamagazine.org/mathematicians-disprove-conjecture-made-to-save-black-holes-20180517/ Whoa. I didn’t know about the Cauchy horizon.
Math Problems
Michael Cooney writes for Hewlett Packard Enterprise about The toughest math problems that challenge the world https://www.hpe.com/us/en/insights/articles/the-toughest-math-problems-that-challenge-the-world-1805.html I have no idea about them, unfortunately.
How Poetry and Math Intersect
An article by Evelyn Lamb about the unusual couple poetry and math. How Poetry and Math Intersect https://www.smithsonianmag.com/science-nature/how-poetry-and-math-intersect-180968869/ Not sure what to think about this. Poetry was never of much interest to me.

Faith in p values
Steve Luck writes about loosing faith in p values. Why I’ve lost faith in p values https://lucklab.ucdavis.edu/blog/2018/4/19/why-i-lost-faith-in-p-values The title of this article is very interesting. A lot of calculations today depend on statistics and p values, I think. Do we have faith in their […]
