Great news: a scientific article I have co-authored has been accepted for publication and can now be found online here or via the DOI 10.1016/j.spa.2020.01.011. Yes, my list of publications has been amended 1. This article has been through quite a lengthy review process, and was the main motivation for another one of my blog posts. This post dates to September 2018, yet I only started working on these simulations in the framework of the second round of peer review.
A Standard Problem: Determining Sample Size Recently, I was tasked with a straightforward question: "In an A/B test setting, how many samples do I have to collect in order to obtain significant results?" As ususal in statistics, the answer is not quite as straightforward as the question, and it depends quite a bit on the framework. In this case, the A/B test was supposed to test whether the effect of a treatment on the success rate p had the assumed size e.
On this page I have collected the bibliographic details of all the articles I have written, mainly of scientific (i.e. statistical) nature. I have written almost all of the scientific papers while under contract at a public university, either in Darmstadt or in Heidelberg. I have submitted all papers to journals which are edited and refereed by other scientists in presumably public institutions. Yet, for some reason, the results of the publically funded, publically relevant1 research is NOT officially publically available.
Update 2018-02-17: The title of this article has changed reflecting new information I have received since publishing. For mor information, I refer to the last paragraph. A treasure trove of leaked passwords The API of pwnedpasswords.com is quite remarkable. It not only allows you to fetch the results generally obtained by typing in your e-mail into the browser interface and finding out whether or not you've been pwned from the comfort of your shell.
The Final Result Let me start this article by showing you my usage of the functionality described. I work as a Data Scientist and use org-mode in Emacs for a large number of every day tasks. One of them is the documentation of new findings within datasets or other software's documentation or websites etc. In order to easily collect all these informations into a single reference, I like to use screenshots:
The Setting: Avoiding 4 Weeks of Runtime Recently, I was faced with a problem: I had written a rather complex simulation of a discrete time queueing network, and I needed to let this simulation run with some repetitions of the entire simulation, for some varying different parameter values, with many observations (i.e. ~ 2.000.000 observation). The goal was to verify that a new estimating procedure for such queueing networks provides sensible results.
Suddenly, Attention So, it seems like my blog is getting some attention. Recently, I was even featured on the front page of Hacker News: Number 17... only 16 more to go! Obviously, I am delighted and flattered by the number of people reading and discussing my blog. But since we're living in a material world, and I am a material guy, I kept on wondering "is there any way to monetize this in an ethical way?
