Join Barton Poulson for an in-depth discussion in this video Sequence mining in R, part of Data Science Foundations: Data Mining.
- [Voiceover] Now we're going to be doing an analysis…to check for changes in response methods.…We're going to use something called a hidden Markov model,…and what that does is it looks for whether people are…changing between different states or different…methods of responding.…The data set that we're going to be using is speed.csv.…It's about reactions to a judgment task…in a psychology experiment.…And the idea is that people are either responding quickly…or they're responding accurately,…that there are these two qualitatively different methods.…
And we're going to use the hidden Markov models…to see if two different states matches the data.…We're going to first load two packages:…pacman, to simply manage the packages, but also depmixS4.…That's the one that's going to allow us to do…the hidden Markov model.…And I'm going to be using a data set that's…from that package called speed,…and I'll be using that, by the way,…in my other demonstrations, but I'll be…importing it as a CSV in those ones.…So let's take a quick look at speed.…
