Exercise

Plotting a Bayesian model

In previous exercises we have estimated a Bayesian model predicting a song's popularity (popularity) from its age (song_age). Now let's visualize the model. Using the songs dataset and stan_model object that are already loaded, create a visualization showing the data the estimated regression line using ggplot2.

Instructions

100 XP
  • Save a tidy summary of the model parameters to tidy_coef
  • Pull out the estimated intercept and slope from tidy_coef
  • Create a plot showing the data and estimate regression line with song_age on the x-axis and popularity on the y-axis
