Causal Impact

Today's episode is all about Causal Impact, a technique for estimating the impact of a particular event on a time series. We talk to William Martin about his research into the impact releases have on app and we also chat with Karen Blakemore about a project she helped us build to explore the impact of a Saturday Night Live appearance on a musician's career. Martin's work culminated in a paper Causal Impact for App Store Analysis.

William Martin: I completed my undergraduate degree at UCL in 2012 in Computer Science. I worked with others on the Newton Spectrum corpus browser, and then extended the system to incorporate a topic modelling based cluster visualisation. In my final year I worked on an automated method for correcting topic model coherence through external bias. I am currently a PhD candidate in Computer Science at UCL Crest centre, in the area of App Store Analysis.
