After publishing a research paper describing the results from the model fitted for Question #3, you are contacted by 20 other large hospitals, and they wish to contribute to the estimation of a model for predicting birth weight. The team agrees that estimation of the variance in expected birth weight between hospitals and explanation of that variance with hospital-level covariates is a key objective. What type of model would you fit?
