Calculating the LOO estimate

Now let's practice using the loo package on our Spotify model so that we can determine which model provides the best fit to our data. The songs dataset is already loaded.

Exercise instructions

  • Estimate a model predicting popularity from song_age
  • Print the LOO approximation for this model with 1 predictor
  • Estimate a model predicting popularity from song_age, artist_name, and their interaction
  • Print the LOO approximation for this model with 2 independent variables

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Estimate the model with 1 predictor
model_1pred <- ___(___ ~ ___, data = songs)

# Print the LOO estimate for the 1 predictor model
___(model_1pred)

# Estimate the model with both predictors
model_2pred <- ___(___ ~ ___ * ___, data = songs)

# Print the LOO estimates for the 2 predictor model
___(model_2pred)
