Determine which model works best for features: [PS, T, U, and V] and label: PTTEND
PTTEND (T total physics tendency) is the result of the CAM's processing of the PS (surface pressure), T (temperature), U (zonal wind), and V (meridional wind) input variables. This is a linear function.
We assume this process is suited to a simple linear regression model.
Score various linear models and corresponding parameters to determine which works best for these features/label.
