117 Calculating probable limit of error for carbon stock estimates
The probable limit of error around mean carbon stock values for a set of plots within a stratum is to be calculated using the following formula:
| | Equation 28 |
| = | probable limit of error for the jth stratum for the reporting period, as a percentage. |
|---|---|
| = | standard error for mean plot carbon stock for plots within the th stratum for the reporting period, in tonnes per hectare of CO2‑e (t.ha‑1 CO2‑e), calculated in accordance with Equation 11b. |
| = | two‑sided students t‑value for the 90% confidence level at the appropriate degrees of freedom ( ‑1), where n is the number of plots assessed in the th stratum during the reporting period. |
| = | mean plot carbon stock for plots within the th stratum for the reporting period in tonnes per hectare of CO2‑e (t.ha‑1 CO2‑e), calculated in accordance with Equation 11a. |
