1/6 #OrderBookAnalysis 🧵

TLDR: Liquidity=Sentiment

2/6 Analyzing the order book with a #DataViz tool like #FireCharts helps you mitigate risk by replacing speculative decisions with data based decisions.

No reason to speculate when you can literally see where higher concentrations of liquidity mark resistance and support. #FireCharts 2.0 (beta) show...
3/6 Knowing where liquidity ISN'T, is as important as knowing where it is. Thin liquidity indicates zones with greater potential for volatility since price moves through them with less friction.

I used to think tables are boring.

But they can be beautiful & engaging.

Here's a nice example from @infobeautiful.

It uses many eye-catching elements but you don't need them to create a great table.

Let's start with a not so great table and improve it.

Here's a table I would have created just a few months ago.

Not so sexy, right? Let's clean that up. Image
1. Avoid vertical lines

The above table uses waaaay to many grid lines.

Without vertical lines, the table will look less cramped.

Have a look for yourself. Image

1/10: 🧪📊 Introducing Generalized Linear Models (GLMs) and how to perform them using R! A thread. #GLM #Rstats #DataScience Source: https://towardsdata...
2/10: 💡GLMs are a general class of regression models that extend linear regression, allowing for a variety of response distributions & link functions. They're used for modeling relationships between a response variable & one or more explanatory variables. #RStats #DataScience
3/10: 📐The main components of a GLM are:

Random Component: The response variable's distribution (e.g., Gaussian, Poisson, Binomial)
Systematic Component: Linear predictor (linear combo of explanatory variables)
Link Function: Connects the two components. #Rstats #DataScience

A STN lança hoje a história “Deslocamentos e gastos hospitalares dos municípios brasileiros”, que traz dados sobre deslocamentos feitos por cidadãos em busca de tratamentos de saúde não fornecidos em suas cidades de origem.
#rstats #dataviz #EconTwitter

… ImageImageImageImage
Constatou-se que cerca de um terço dos atendimentos médicos foi prestado a pessoas de outros municípios. A cidade brasileira que mais recebeu pacientes de outras cidades foi Recife, superando inclusive São Paulo em valores absolutos. #atendimentohospitalar #Recife #SãoPaulo Image
Os dados foram obtidos da base de atendimentos hospitalares do DATASUS, em cruzamento com os dados do IBGE e da STN. A maioria das cidades de pequeno porte possui gastos bastante inferiores às de médio e grande porte. #opendata

50 years ago statistician Frank Anscombe warned us that #dataviz is essential to good statistical analysis

To demonstrate the point he generated what is now known as “Anscombe’s quarter”.

Four datasets that share 10 statistical measures but are from different populations (1/2)
In 2016 @AlbertoCairo produced the Datasaurus Dozen to make this point even more dramatically.

It’s absolutely wild that 50 years later we still need to communicate this to folks who have recently awarded STEM degrees.

Dataviz needs to be a fundamental part of data education
But also, we need to be forgiving of instructors who already have overburdened syllabi and would find it hard to include more than a passing mention of this issue.

Just like we need to be forgiving of me missing the actual 50 year anniversary by 4 days 😬

How should you 𝐥𝐞𝐚𝐫𝐧 𝐏𝐨𝐰𝐞𝐫 𝐁𝐈? 🚀

It's easy to be overwhelmed by how broad #PowerBI is😖

If you're starting out, here's the path I recommend⏬

Begin by learning to organize data into tables, create relationships, and add calculated columns and measures.

This is the most important part of your journey, as understanding the #data is always the first step in Power BI development.

Untuk edisi #rabuTableau minggu ini, gue mau bahas soal data preparation atau persiapan data. Meski beberapa bagian di thread ini spesifik untuk digunakan untuk Tableau, namun banyak poin yg bermaanfaat untuk analisis data juga kok.

Mari kita belajar ngolah data! 📊
Biar lebih paham, sebelum berkutat ke tools @tableau atau @tableaupublic , gue mau sharing dulu apa itu data preparation.

Lo bisa simak gimana prinsip-prinsip mengolah data supaya bisa digunakan dengan layak nantinya.
Proses data preparation itu termasuk tahapan penting. Tujuannya agar data yg kita punya reliable. Selain itu, data juga bisa dibikin lebih ringkas, biar nantinya kita ga pusing atau repot sendiri saat dikulik.

Biar lebih paham, coba perhatikan gambar di bawah ini:

Hugely important insight here for analysts and data scientists. It isn't enough to know the right answer: you have to persuade people to pay attention to it...
This is a big problem since the group of people who have the insights (the analysts) are often the least effective at persuading decision makers to pay attention and actually make different decisions...
Analysts are often introverts and often focus on the art of analysis (getting the right answer) rather than the much wider job of persuading the people in power to make the right decisions...

What is the most successful Hollywood movie of recent times? Everyone says and thinks Avatar right? But, as ever, it depends how you look at it.

We took a deep data dive and found some surprising, nay *horrifying* answers…(1/18)
#Avatar (2010) grossed close to $3bn worldwide, very closely followed by Avengers: Endgame at $2.8bn. Avatar 2 is currently at ~$2bn. While still climbing, it’s doubtful it will beat out its predecessor (2/18) Image
Note this steady, beautiful trend of films earning more and more… Might be a sign of rising returns. Or could be a side-effect of our old friend INFLATION 📈 So our first step: inflation adjust the data (3/18)
