Plotting Model Uncertainty
Because we used a Bayesian estimation, we can use the posterior distributions to create a predicted regression line from each draw in our posterior samples. These lines will show the uncertainty around our overall line. The songs and stan_model objects are already loaded, along with the model_intercept and model_slope that you used in the last exercise.
