De Econometrist neemt een statistische kijk op de wereld.
During the 2008 financial crisis, the US housing bubble collapsed since homeowners could not repay their loans, which forced the US government to bail out financial institutions that were “too big to fail” with 21 billion dollars tax money. While we are already in a new financial crisis due to Covid-19, another financial crisis may be looming and the potential permanent damage of this crisis would far eclipse the scale of the 2008 financial crisis. The cause of this financial crisis is climate change, due to which for instance, wildfires, catastrophic floods, droughts, or storms […]

It is no surprise that the 19th century was a time of scientific breakthroughs and wondrous inventions. However, for the people of Philadelphia, this meant that for only one dollar they could admire the most amazing machine in the world: a machine that stayed in motion forever without any external source of energy. The inventor of this device was a gentleman called Charles Redheffer, and his invention attracted a lot of spectators from all over the state. His machine stayed in motion due to two weights which, using gravity, pushed a large horizontal gear away […]
On the 6th of may 2017, I woke up early in the morning to watch a special race: the sub-2 hour project announced by Nike. During my breakfast, a very special athlete was cruising at a pace of around 21.1 km/hour on a race track in Monza, Italy. Guided by pacemakers and an electric car that projected the formation the runners had to run in, Kipchoge was going to do something very special. Inspired by this event, I decided to go for a jog myself. When I came back, Eliud Kipchoge finished the marathon in […]

Computers are taking over manual labor at an unprecedented rate. Currently, 29% of all labor is automated. It is expected that, in the US alone, 38% of jobs are automated by 2030. This increasing level of automation also paves the way for new forms of attack by domestic or foreign actors: cyber-physical attacks. Stuxnet In 2010 a new kind of computer virus was discovered in nuclear facilities in Natanz, Iran. The virus targeted PLCs (programmable logic controllers) that controlled centrifuges in uranium enrichment facilities. It is widely believed that the virus’ primary target was the […]
In statistics we are often estimating parameters and then, using some hypothesis test, we can find out if we should either reject our null hypothesis or not. Now in these tests we almost always rely on some known distribution of a so-called test statistic. Let us start by looking at an example of such a test. We will first need to assume that our sample follows a normal distribution with a known variance. Now we want to test if the mean of this normal distribution is equal to . Hence, we conduct the following test: […]
Remember those good old times when you could just use an all lowercase letter password of just six characters? You might have to bury deep into your memories, since those times are long gone. For me, the last such password I can remember, was my password for Spele.nl ten years ago. Back then, I could simply use turnen as my password, since that was my favorite sport. However, nowadays you need to include both lowercase and uppercase letters, characters, and numbers in your password, which also needs to be at least eight characters long. Why […]
