EREM (Egocentric relational event model) working example following Marcum & Butts (2015)
This is an intructory tutorial on egocentric relational event modeling (EREM) going through the worked example in Marcum and Butts (2015) using their informR package and the relational event modeling package “relevent”. You can find the original paper and source code at Marcum & Butts (2015). The main difference here is that I’ve added interleaved my comments with the code. The example will however make a lot more sense if you read through Marcum and Butts’ paper first (and they also go into a lot more detail).
