In my last post, I discussed the experimental design for comparing the effect of an event on two groups (treatment and control groups). The example showed no significant effect, i.e., no difference between the groups, for the intervention discussed. But is this true? The result could be correct and there...
Motivation In the last article, I discussed how to implement a simple model to judge the (linear) relationship between two or more variables. In this article, I will walk you through a simple yet powerful tool for judging the difference between groups. In an ideal world, we would like to...
For many real-life questions, we are interested in the relationship between two (or more) parameters. Typical questions are: This article shows how to approach such questions using the simplest model. A model that assumes a linear relationship between the outcome (the thing that is affected) and the regressor(s) (the thing...
In this article, I will walk you through the steps to create a prototype of an R project with pipeline integration, package management, and version control. If you follow these four simple steps, you will be well prepared to tackle any (data-driven) question that comes your way. With version control...
A friend asked me to create an interactive map for her. The task was to show places of the democratic movement in Leipzig (Germany) that could later be hosted on a website (Don’t worry, you don’t need to know German to follow along). The map provides information about where these...
For one of my research projects focusing on tax cuts in the fuel market (if you are interested, drop me a line), I had to repeatedly calculate the price reductions and the pass-through rate of the tax cut. So, I took the opportunity to try out the Python library Tkinter....
Open Street Map (OSM) data can be a highly useful tool for obtaining spatial information about your local community. Next to its broad availability, it can be easily obtained via Python. This article shows you how to download OSM data as the one mapped below. The figure shows restaurants in...
When traveling through Germany, you might gain the impression that many cities in a particular region have similar names. A pattern that emerged through historical and geographical circumstances. As the country was divided into many smaller entities over centuries, different regions developed their own dialects leading to specific wording. I...
