43  Regression estimate of sampling variance of mean carbon stocks within a stratum
  Work out the regression estimate of sampling variance of mean carbon stocks for each stratum h in the CEA (the Reg for the sampled and modelled carbon stocks in the CEA (tonnes of soil organic carbon per hectare)2, using the following equation:
   equation 107

              where:
               is the identifier for each stratum in the CEA.
              is the sampling fraction for the stratum h, worked out using equation 100.
               is the number of model-validation samples collected from the stratum h.
 is the variance of the mean soil organic carbon stock for the stratum h, worked out using equation 98.
 is the regression coefficient for the modelled and sampled carbon stocks in the CEA, worked out using equation 103.
 is the covariance of the sampled and modelled soil organic carbon stocks in stratum h, worked out using equation 106.
V is the variance of the mean modelled soil organic carbon for the model-validation sites for each stratum h, worked out using equation 105.
