Table 1. Performance of random forest models trained on different age ranges.

RF Models Trained on Different Age Ranges
Age Range	Mean Absolute Error	R2
1-17 years	0.87	0.94
18-44 years	5.15	0.44
45-64 years	2.20	0.77
65+ years	4.30	0.25
1-85 years (Overall)	4.76	0.92

Random forest models were trained on data from individuals across different age ranges within the dataset. Mean absolute error and R-squared are shown in the table as measurements of model performance on held-out data.
