Galveston: In 1900, Galveston, population 36,000, was obliterated, making it the site of the worst natural disaster in US history, a sad record it retains to this day. 6,000 to 12,000 were killed, thousands of buildings wiped out, etc. 1/
2/ Galveston was rebuilt with a massive seawall and the land was raised as much as 17 feet. 15 years later, another similar hurricane and storm surge hit. The wall worked. Only 53 were killed. #Galveston #Texas #hurricane #UShistory

✔️ The difference between correlation and regression: towardsdatascience.com/the-difference…

#Correlation #Regression #Statistics #DataScience
1. Correlation: Correlation is a statistical measure that expresses the linear relation between two variables.
2. Regression: Regression analysis is a mathematical technique used to analyze some data, consisting of a dependent variable and one (or more) independent variables with the aim to find an eventual functional relationship between the dependent variable and the independent ones.

Debunk on the #pfizerdocuments . They mean nothing. I’ll tell you why. But first here is the link to the original paper:
phmpt.org/wp-content/upl…
If you read them, You will find 42.086 #notifications concerning possible side-effects and a checklist of possible adverse-effects which #Pfizer looks for in the trials (starts page 30)
These adverse-effects are different then side-effects. They haven’t happened, are only mentioned as things to look out for and prove that #Pfizer is thorough in their #testing and #research.

Finally, the #GoldacreReview is published! (During Parliamentary Easter holidays, mid-ping-pong on the #HealthAndCareBill...)

It's 221 pages - each PDF page is a double page spread - so this could be a lo-o-o-ong [Thread].

Here goes...
First point to note, in the Terms of Reference (p5), is that this is about "access to #NHSdata by #researchers, #commissioners, and #innovators" - i.e. #Planning and #CommercialReUse - so it is directly relevant to the operation of millions of people's #NationalDataOptOuts...

"systems that ensure #underrepresented groups are well represented" may (partly) refer to this "landmark review", which got off to a slow start:

Yesterday I shared a small thread about getting into #DataScience. Today I’ll build on that and share a bit about my own journey into sports analytics, specifically as a #DataScientist in the #football industry. 🧵
My path began with a MSc in Sport & Movement Science @VU_FBW. It’s not computer science or anything, but it does involve quite some #Math, #Statistics and #Physics, as well as a course in programming. Mainly it learned me Science, and gave me a lot of domain knowledge in sports.
I wasn’t planning to become a #DataScientist, but I wanted to work in sports. I did various stints as an embedded sports scientist, mostly internships/part-time, before joining @ZZLEIDENBASKETB. Those jobs involved data & science, but it wasn’t anything close to #DataScience.

Enamorarse hace que las células del sistema inmunitario se comporten diferente 💘🧬

Un grupo interdisciplinario de investigación en Estados Unidos reportó que algunos genes aumentan su expresión y otros la disminuyen cuando hay un enamoramiento 😍

Primero un pequeño recordatorio sobre la expresión génica:

Los seres vivos guardamos la información para construir todas nuestras proteínas en nuestro material genético, el #ADN🧬. El cual está dividido en secciones llamadas genes

2/12

#GeneExpression #Biology
Para que la información de un #gen se traduzca en la producción de una proteína es necesario que primero se transcriban las instrucciones en una molécula de #RNA mensajero (#mRNA) que la célula pueda leer

A la producción de ese mRNA le llamamos expresión génica

Ahora sí..

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):

What a fantastic way to start a week!

Thank you to @sallycmorton and @FDuBoisBowman for visiting us in the COPSS @COPSSNews leadership academy yesterday!

A short 🧵 on how these meetings came about and few things I learned from these wise folks.

1/n
First, the zoom meeting (pictured above) took place because of the visionaries @BhramarBioStat and Huixia Judy Wang, who conceived the idea of the COPSS Leadership Academy and brought it to fruition!

2/n
The purpose of this award is to "recognize early career statistical scientists who show evidence of and potential for leadership and who will help shape and strengthen the field".

Some coal mining fatality numbers. With China coal in focus, couldn't help but thinking how 20 years back, there seemed a tragic coal mining accident every month on Chinese news. Yet this year, the biggest tragedy seemed to be the frozen to death Marathon runners in Gansu. /1
Typically US has the best open data, with No. of miners and deaths decreasing significantly. %of death has plumeted too, with 0.01% of miners death in the US, which with <100k miners means <100 people each year. /2
According to Ministry of Emergency magt. end of last century annual deaths were 9506, but lowered to 316 in 2019. The lower death also partly due to smaller number of miners in China which is about 3473k now.

🧐If recently vaccinated keep dying, why not call them “unvaccinated” until we know they’re gonna make it?

5-6 weeks of Vx death stats immunity? Or two 14-day periods?

Are there #data studies and #research on most effective ways to share info about the vaccine? I've been having lots of convos with vaccine hesitant ppl and a common thing is no data culture, so they don't understand the #chart + #statistics . So, what did I do ? 1/
I asked vaccine hesitant ppl questions instead of throwing info at them. Showing up saying "Look at this data!" isn't helpful, or working. We all have different approaches, values, and things that resonate. Do you want to be told you're right, or do you want to be effective? 2/
I started asking vax hesitant ppl questions after our talks, too. What did I say that landed? How did you feel about this fact? When did I say things that frustrated you? What info had you heard before, and what was new? How do most people approach you? How are you irl? 3/

First speaker is @AyisSalma, reflecting on the subtle but important difference of what we think and what data are.
#COVID19 statistics are easily misinterpreted Image
Statistical anomalies in calculations of #COVID19 infections and deaths meant it appeared that no-one ever recovered!
And these figures influenced government #publichealth decisions Image
