estimation event, then Subdivision 4 of this Division must be applied to the model-validation samples, and, for the CEA for the reporting period:
 (a) is the Reg for the CEA, worked out using equation 104;
 (b)  is the  for the CEA, worked out using equation 108; and
 (c)  is worked out using equation 109.
Note:  This applies a model-assisted approach to soil organic carbon stock estimation which uses samples in conjunction with modelled estimates to provide an estimate with potentially lower sampling variance than using samples alone. The approach is also used to calculate statistics that may be relevant to other CEAs using a model-only approach under subsection (4). The model requirements are set out in the Supplement. If model calibration samples were also collected from the CEA, subsection (2) will also apply, with the resulting estimates being compared under subsection (2).
