  3. Bayesian Regression Modeling with rstanarm

Exercise

Unadjusted Priors

Now let's specify a model that doesn't use adjusted scales for prior distributions, so that we alter rstanarm default behavior. This will allow us to have more direct control over the information going into the estimation. The songs data is already loaded.

Instructions

100 XP
  • Predict popularity from song_age
  • Tell rstanarm not to autoscale the parameters
  • Print a prior summary to confirm there was no adjustment
