In this part of the data visualization project, we will review charts that help find similarities and differences between various categories of data and discuss their purposes and specifics.But firstly, let’s sort out what a discrete data is.What is discrete data?Data is discrete if you can answer affirmatively on the following questions about it:Is it countable?Is it possible to divide the data into smaller parts? (i.e., to categorize it)Discrete data can contain only a finite number of values. One of its notable properties is that, unlike continuous data, it can’t be measured, only counted.Examples of discrete data: the number of players in a team, the number of planets in the Solar System.Examples of non-discrete (continuous) data: height, weight, length, income, temperature.Bar chartThe (...)

Three out of every two people struggle with fractionsEach week for the last 6 years (2012–2018), I was playing the lottery to win. Not just hoping to win — playing with a ‘positive expected value’ (a mathematical expectation to win rather than lose, on average, over time). In June 2018 this particular window of opportunity closed, so I’ve decided to share more about the winning model and reveal some closely guarded secrets from the clandestine world of professional #gambling.Oz Lotteries ‘Pools’ website one day after the game was discontinuedWinners walking among usWe’ve all heard the maxim ‘the house always wins’.

Sure, I sit in a cubicle part-time coding my life away, but there are moments where people step out of their hole to converse with those around them.One of these structured ways is through the weekly update meetings, and one of the many conversations we have inspired this post.Let’s start off with statistics.One of statistics’ main focus is to create a generalizable model, such as a linear or multivariate regression model, to best fit the data to represent the pattern you are investigating.There are other key topics in statistics like statistical significance, correlation vs. causation, probability theory, and model evaluation that are shared (...)

Data analytics is one of the fastest growing jobs. But, you can be even more successful in it with at least some knowledge of economics. In particular, these techniques can help you create your own mini research lab in your startup so that you have the resources of a large company to produce useful business intelligence analysis, while still remaining agile and lean.Having finished my doctorates in both a traditional economics and a less traditional computer science-ish department at Stanford, I’ve had the opportunity and pleasure to interact with a wide range of quantitative data science techniques. Both departments have different styles, but their approaches are highly complementary, which is being increasingly recognized by economists, such Susan Athey and Sendhil (...)

Bootstrapping/Bagging/BoostingMachine learning and data science require more than just throwing data into a python library and utilizing whatever comes out.Data scientists need to actually understand the data and the processes behind the data to be able to implement a successful system.One key methodology to implementation is knowing when a model might benefit from utilizing bootstrapping methods. These are what are called ensemble models. Some examples of ensemble models are AdaBoost and Stochastic Gradient Boosting.Why use ensemble models?They can help improve algorithm accuracy or improve the robustness of a model. Two examples of this is boosting and bagging. Boosting and Bagging are must know topics for data scientists and machine learning engineers. Especially if you are planning (...)

Let’s say a group of researchers, or #data scientists discover that the mortality rate in Florida is 20 deaths out of 1000 people a year compared to Washington State where it is 9.8 deaths out of 1000 people.Being very concerned these researchers put in a proposal for millions of dollars to try to figure out how to decrease this mortality rate in Florida. However, they forgot to dig a little deeper. They forgot to exam the average age of the populations of the two states. If Florida’s average age is 52 and Washington’s is 25 that might play a role in the mortality rate. In this case, the age played the role of a confounding variable.A variable that is not considered but plays a role in the outcome of an event is considered a confounding factor.In epidemiology, a confounding variable refers (...)

Les ravages de la fétichisation des p-valeurs et du biais de publication, en une diapo :

Dans le contexte de la vidéo, ’truquée’ = hypothèse réellement fausse, ’Équilibrée’ = hypothèse réellement vraie.

Je l’ai trouvée particulièrement claire, c’est facile de s’emmêler les pinceaux quand on veut expliquer les tests d’hypothèses. Le papier de Ioannidis va plus loin en terme de modélisation mais cette approximation est suffisante pour une exposition rapide.

Let’s get into the topic fast. I know, you don’t have time. You have to learn other topics too. Okay! I hear you :)CONTINUOUS VARIABLEA continuous variable can take any values. Think of it like this: If that number in the variable can keep counting, then its a continuous variable.Ex: Weight of a person: 152.232 Kg, you’re probably thinking, “where am I counting?”. Yes, you are! The weight of the person is actually 152.232211223342211223332112244778899399947777889999888888377747666678788992336677……………………………………………………………………………………………………………………………………………………………………………………………………………………………………KgObviously, those dots aren’t ending anytime soon. Matter of fact, they’re not ending!Now you see how specifically that variable can “keep counting”? When I say “counting”, I’m referring to those counts after the decimal.That is an example for (...)
