45  Degrees of freedom for the regression estimate of sampling variance of mean carbon stocks in the CEA
  Work out the degrees of freedom ( to use in equation 115 for a given estimation event, using the following equation:
  equation 109

where:
 is an identifier for the stratum.
H is the number of strata for the CEA.
 is the relative area of the CEA covered by stratum h in the CEA, expressed as a proportion of the total CEA area.
 is the regression estimate of sampling variance of mean carbon stocks for stratum h in the CEA, worked out using equation 106A, in (tonnes of soil organic carbon per hectare)2.
   is the number of model validation samples collected from the stratum h.
Note 1: Equation 109 is a simplified equation using the condition that  The original version of the equation is:
Note 2: Where a CEA contains three strata, equation 109 written in its expanded form, where the subscripts 1, 2, and 3 are used to denote values for stratum 1, stratum 2, and stratum 3, respectively takes the following form:
