Master data cleaning in pandas like a pro with these simple functions.

Data cleaning is a critical step in any data analysis project

Learn to clean messy datasets with these easy steps.

A thread🧵👇 Image
In pandas, you can use functions like .dropna(), .fillna(), and .replace() to clean up your data.

For example, let's say you have a data frame with missing values like this: Image
1. The .dropna() function removes any rows with missing values.

For example, you can use df.dropna() to drop any rows with missing values from your data frame called "df": ImageImage

As you may know I have been scraping & compiling tweets about Donald Trump weekly

#Vader Sentiment Analysis says that this latest batch of tweets, based on the same keyword list, classified the majority of the tweets as POSITIVE

pos 61608
neg 53446

This bucks the trend Image
The averages are interesting, a sort of inverted bell curve where most tweets have a few re-tweets, views etc. and then the opposite end of the spectrum where a minority have a TON of views, likes, etc. or none at all

The replies seems weirdly low, I'll double check that. Views are easily the data point with the highest volatility.

❗️trigger warning ❗️
Paediatric acute-onset neuropsychiatric syndrome secondary to Covid-19. (PANS)

Anna is very distressed in these videos.
I have met Anna and she is a quiet, observant girl.
She should be enjoying life right now.
Instead, due to Covid, she has lost years.
Only due to her Mum’s persistence has she got a diagnosis and treatment.
This happened before Covid to children BUT we don’t know how many children have been affected now.
Who is counting this Covid sequelae? CAMHS? Paediatrics?
It’s hard enough to find a dr to diagnose it.
It is caused by inflammation in the brain.
It’s autoimmune- think of a condition like rheumatoid arthritis but the brain is affected not the hands
It is often misdiagnosed as primary mental health disorder.

Resolvi pegar os dados do gráfico do índice de liberdade econômica e fazer um analise correlacional, primeiramente nada conclusivo ai meti um média móvel...
Xablau a mágica se fez!

#DataScience
#dython
#pandas
#Politica
#Economia ImageImage
Gráfico da esquerda é do média móvel da nota .
Qual presidente está no poder tem um correlação forte com a liberdade econômica, agora qual presidente e em qual mandato tem correlação altíssima.
E explica também a diferença ou seja a direção pra onde se vai, se melhora ou piora.
A correlação ai zerada entre a nota geral e a diferença ano a ano tanto quanto a mudança percentual mostra que não tem autocorrelação na variável. Não é porque a nota é alta que vai ter tendencia a subir ou descer o que pra mim reforça ainda mais a correlação anterior.

🚨 Did you know common infections can cause severe mental illness that’s mostly overlooked by MDs?

@krisnewby wrote abt stunning case of healthy teen dx’d w schizophrenia after bug bites transmitted #Bartonella.

He was committed to psych ward...

nowthisnews.com/swamp-boy
He failed all major psych drugs & only got worse.

His dad had hunch that docs were missing something important & began reviewing literature.

He presented MDs w his findings of infection-mediated illness #PANS.

MDs wrongly dismissed him, insisted it was psychiatric.
Dad was right.

His research led him to the work of brilliant Dr Ed Breitschwerdt from @NCStateVetMed , 🌍 leading expert on bartonella, who I interviewed last week (will post link).

He contacted Dr B whose lab found bartonella in his blood.

Panda-Diplomatie: Der #Panda ist ein erfolgreiches Soft-Power-Tool Chinas. Seit 2017 lebt ein Panda-Paar im Berliner Zoo. Dokumente, die @FlorianFlade u. @PinkertReiko vorliegen, zeigen, wie sehr sich Deutschland um die Leihgabe aus #China bemühte. Sogar die Kanzlerin persönlich. Image
Unterlagen aus dem Bundeskanzleramt und der Berliner Senatsverwaltung, die #NDRWDRSZ vorliegen, dokumentieren, wie die Berliner Landesregierung das Kanzleramt unter Merkel überzeugen konnte, sich für die #Panda-Leihgabe einzusetzen. Wir veröffentlichen die Dokumente hier. #IFG
Die Dokumente verdeutlichen, wie aus einem Anliegen der Berliner Politik geradezu ein weltpolitisches Unterfangen wurde, um das politische Klima zwischen Deutschland und #China zu verbessern - die sogenannte #Panda-Diplomatie.

Data analysts should be able to efficiently build datasets using the content on the web.

Here I will show you a use case for a small script I created that allows the user to build corpora of textual information from online blogs.

People working in #seo can definitely use this👇
It is a #Python script that efficiently organizes data in a #pandas dataframe for ease of use and readability.

It leverages Trafilatura, an open source library that is able to read and follow links from the website's sitemap and identify the main content of a page.
This is particularly important because each website has its own structure and it is often difficult to grab the main content as opposed, for instance, to the sidebar.

Trafilatura uses a series of heuristics to find the main text of the page, and it works pretty damn good.

Across the world, today is #PANS #PANDAS awareness day. My son developed #PANS in December 2018. I will never forget the day and time it first presented itself. I did not know at that time how his and his family's lives would be irrevocably changed 🧵
Right now, my son is doing well. This is because of the help I found via the support network gathered around the UK #PANS #PANDAS charity, PANS PANDAS UK @PandasPans
#PANS #PANDAS are conditions with relatively "simple" treatment approaches. Appropriate & timely treatment is stopped by a lack of knowledge by the clinical population & by a small but influential population of clinicians who decline to treat them. Fig Swedo 2017

Interested in learning more about #DataScience, #MachineLearning or #AI? I’ve got a few places and resources for medics to start with. Anyone can do it with enough time and effort! Soon enough you’ll be making your own neural networks

1/16. A thread 🧵.
2/16. Everyone has their preferences with programming languages. However if you’re starting from scratch, I highly recommend #Python. It is easy to learn, has a wide variety of applications and you will find it is much easier to perform even the most basic of statistics.
3/16. It also gives you access to multiple libraries that are used heavily by the machine learning community such as #Keras, #TensorFlow and #PyTorch.

Les INDEX sous #Pandas sont souvent incompris et mal utilisés

Ils sont pourtant d'une grande aide, surtout si on a besoin de performance avec des dataframes volumineux

L'idée principale est qu'ils vous apporteront de la performance s'ils sont UNIQUES

> Illustration
1/ Sélection de lignes d'un df sans faire appel à l'index

Sur un df de 10.000 éléments, la recherche d'une ligne sans faire appel à l'index prend 373 µs (sur mon laptop)
2/ Sélection de lignes d'un df avec appel à l'index

Sur un df de 10.000 éléments, la recherche d'une ligne en utilisant l'index prend 60 µs

Soit un facteur 6 entre les 2 méthodes

This is the kind of paternalistic, unscientific nonsense that #MECFS #Lyme #Fibromyalgia #HSD #POTS #MCAS #Pandas #Pans #EDS #VaccineInjured #FQtoxicity patients have endured for decades. Now it’s the turn of #LongCovid
I’m going to make an offer to our colleague. Hopefully @DrKGregorovic can convey this message as I am blocked. Happy to have a Zoom coffee with both of you. We can examine
-the paper @awgaffney has tweeted & discuss the flaws
-the evidence for biomedical causation in #MECFS & LC
-the evidence for the ‘false sickness beliefs’
-the quality of the studies advocating exercise & talking therapies
-studies looking at the outcome of exercise in #MECFS & #LongCovid populations
-cardiovascular & other outcomes in #LongCovid

I think that is fair? Let me know

But what p-value means in #MachineLearning - A thread

It tells you how likely it is that your data could have occurred under the null hypothesis

What Is a Null Hypothesis?

A null hypothesis is a type of statistical hypothesis that proposes that no statistical significance exists in a set of given observations.

A P-value is the probability of obtaining an effect at least as extreme as the one in your sample data, assuming the truth of the null hypothesis
