Altering the Estimation
Now let's alter the estimation options so that we can be prepared to resolve errors that may arise. It's important for these errors to be resolved if they come up so that we can be sure we are making valid inferences. The songs
data is already loaded.
This exercise is part of the course
Bayesian Regression Modeling with rstanarm
Exercise instructions
- Estimate two models predicting
popularity
fromsong_age
- In the first model, set
adapt_delta
to 0.99 - In the second model, set the
max_treedepth
to 15 - View a summary of each model
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Estimate the model with a new `adapt_delta`
adapt_model <- ___(popularity ~ song_age, data = songs,
___ = list(___ = ___))
# View summary
___(adapt_model)
# Estimate the model with a new `max_treedepth`
tree_model <- ___(popularity ~ song_age, data = songs,
___ = list(___ = ___))
