title: Bayesian knowledge tracing using R
body: <p>I've been trying to use R to estimate BKT group parameters. I found the following site, which seems like it might be helpful to do this:</p>

  <p>However, I'm having a lot of trouble applying this to all the KC's for my data. Has anyone else done something like this and would like to explain how to go about doing it?</p>
  
  <p>Additionally, if possible, I'd like to find the individualized difference weights after finding the BKT group parameters, but if I could just do the latter right now, I'd be happy.</p>
