The title of this guest lecture (slides) was slightly misleading. It was more about data visualisations in the larger context of statistical analysis.

Internal seminar

COMPSTAT conference

Internal talk at Open Lab

This talk (slides) is based on our JASA paper on a hierarchical model of nonhomogeneous Poisson processes (NHPP) for Twitter retweets. The main difference with self-exciting processes for e.g. earthquakes is that we know which original tweet leads to the retweets, and such information is utilised fully in the model, making the likelihood tractable.
