Figure 4

Upper panel: Violin plots of ICU length of stay (raw-scale, length of stay < 16 days) and predicted length of stay (raw-scale, < 16 days; determination and validation data sets) for estimators: OLS (raw-scale), log-scale OLS, LMM, and treatment effects regression. Lower panel: Hosmer-Lemeshow (F) test of residuals across deciles of linear-predictor, for estimators: OLS (raw-scale), log-scale OLS, LMM, and treatment effects regression. X-axis, linear predictor; Y-axis, parameter estimates.
