Homeowners' behavior model

Can we statistically estimate homeowners’ propensity to put a property for sale?

The number of transactions in the property market depends on many sectors of the economy. Fundamentals such as demographics, productivity, and income play a significant role in generating volatility in house prices. In general, transactions on the housing market are determined by how quickly houses are sold and at the same time how quickly appear on the market. How quickly houses come off in a sale the market depends on a process involving buyers and sellers. On the other hand, how quickly houses show up on the housing market depends on the decisions of homeowners […]

Rethink the way you think about randomness!

Imagine you get the opportunity to flip a coin for only 1 dollar : if it turns up heads, you win 50% and if it turns up tails you lose 40% of your initial bet. Of course we’re all familiar with calculating expected payoffs: since this bet has an expected payoff of 0.5*1.5 + 0.5*0.6=1.05, you should take it. Right? Well, it might be a little less obvious.   Suppose you flip the coin another time. Your wealth will, depending on the flips, either be 2.25 (two heads), 0.9 (one heads, one tails),  or 0.36 […]

Donald Duck and the magic wheel

Donald Duck, the unfortunate duck that we all know and love, has had it. He angrily shouts at Scrooge McDuck: “every single day I’m brushing coins for you, and yet you barely pay me enough to buy food for my own nephews. I demand a raise!” Scrooge responds: “No way! A lazybones like you should be happy that I’m not firing you! But if you really want a shot at earning more money, you can have this magic wheel that I got from the prince of Farawayland as part of a trading deal. He told […]

Do storks deliver babies?

When you were still a little child, you were probably told that all babies were delivered by storks. Later, when you got older, you found out that this idea is total nonsense. However, imagine that you are still in doubt whether this idea is true, and to discover the truth, you want to use your statistical abilities. As it turns out, from a statistical point of view it seems that storks really do deliver babies. Or does it not? Robert Matthews In the year 2000, Robert Matthews, professor at Aston University, published an academic paper […]

The Birthday Problem

The Birthday Problem

At the World Cup in Brazil in 2014, in 16 out of the 32 teams two players shared the same birthday. Considering each of these selections consisted of 23 players and there are 365 days in a year (excluding February 29), it seems like an enormous coincidence that this was the case for 50 percent of the teams. However, this trivia fact isn’t such a coincidence at all. In fact, the odds of two people in a group of 23 sharing the same birthday is 50.7 percent. This is what we call the birthday problem […]

True randomness

What is true randomness?

The shuffle function on Spotify is an easy way to listen to music without having to pick some numbers. However, once in a while we all seem to recognize patterns in the numbers that we listen to. The shuffle function does not seem to be so random at all, so are these numbers truly randomly picked? This recognition of a sequence is partially caused by the functioning of our brain. It is very easy for the brain to distinguish patterns in seemingly random things like shuffled music or dice roles. Especially when these “processes” are […]

Racisme: hoe groot is het probleem?

Het discriminatie probleem is sinds enkele weken weer volledig aangewakkerd. De hoofdoorzaak hiervan is toch wel de dood van George Floyd. Naar alle waarschijnlijkheid is hij tijdens een arrestatie door een politieagent gedood. Hiervan zijn gruwelijke beelden op het internet verschenen, waarin je de zwarte man herhaaldelijk ‘I can’t breath’ hoort zeggen. Deze beelden zijn viraal gegaan en hebben in veel landen tot rellen en protesten geleid. In Amerika is de ophef het grootst. Zelfs meerdere bekende Amerikanen, waaronder acteurs en topsporters sporen aan om in protest te gaan. De advocaat van George Floyd zegt […]

the math behind poker

The Math behind Poker

Shady men wearing sunglasses, sitting around a table, playing for big pots of money. That is what we often associate with poker when thinking about the game of bluffing. A game where most people think that the essence is to read your opponents, while leaving them clueless about your cards. In reality, this psychological part of the game turns out to be just a small asset of the qualities a good poker player needs to have. Of course, being able to read your opponents is a huge advantage when playing poker, but the use of […]

Neuralink, our new future?

Elon Musk has always been known as a man of revolutionary ideas, but the following idea might be the most revolutionary of them all. Last week on the 7th of May, he joined the Joe Rogan podcast. Here he revealed new details about his company Neuralink. The idea of this company is to implant very thin electrode wires in the human brain. In this way, it can cure almost any disease which has something to do with the brain. Furthermore, these devices would even allow us to communicate with each other without speaking. The technique […]

The ‘New’ normal

The measures taken during the current global coronavirus pandemic will not last for a few more weeks. Instead, these measures may last forever. This pandemic is unlike anything we have ever experienced before. Almost all aspects of our daily lives have been altered to sustain an almost unorthodox way of living. Society has successfully shifted from an open society to one where social distancing is the norm. We have profoundly changed the way we work, socialize, shop, exercise, and educate ourselves. Most of us want things to go back to normal in the coming few […]

Running out of options

During these crazy times, the people that I speak roughly seem to fall in two categories: those who have stopped exercising altogether, and those who actually have been getting fitter in the last two months. The reason for these extremes is the closing of almost any sport accommodation. Besides activities such as skating, walking, yoga or exercise at home, two main sports are left: running and cycling.    As can be seen by data from Strava, an application that tracks your sport activities, these limited possibilities have led to an immense increase in these two […]

The Optimal Pace

For professional athletes, the goal of running a marathon is to complete it as fast as possible. However, this does not mean that the athletes are running as hard as they can all the time, as one cannot maintain this pace the entire marathon. Hence they need to find a maintainable pace at which they finish the marathon as fast as possible: the optimal pace problem. It turns out that this very general problem is occurring far more often in normal day life and in business than most of us realise. Furthermore, it turns out […]
