Podcasts for Data Science Start-Ups
I am not a Podcasts person. Most episodes are too long, there is a lot of nonsense talk with inside jokes, and I usually find information quicker when googling on my own. As the past months have been quite busy, however, I was looking to fill the time where I couldn’t read or do other […]

Over the two months I have learned a lot, exchanged some great ideas with the three of them – and […]

Update on the Replication Bayes Factor
In December I already blogged about the ReplicationBF package, I made available on GitHub. It allows you to calculate Replication Bayes Factors for t- and F-tests. The preprint detailing the formulas for the latter was outdated and the method in the package was not optimal, so I recently updated both.
