 (12) In the case where the option specified in paragraph (11)(b) is selected, no further steps of the validation test set out in this section need to be conducted.
 (13) Once selected in accordance with this section, each test tree must be assessed in accordance with Subdivision 14.
 (14) A predicted estimate of the biomass contained within each test tree must be generated using the allometric function to be validated using as inputs the predictor measures collected from the test trees.
 (15) Using the measured and predicted biomass estimates generated at subsections (13) and (14), the variance of weighted residuals for the set of test trees () must be calculated in accordance with section 122.
 (16) To test for statistical difference between the variance of weighted residuals calculated for the allometric function in accordance with section 65 () and the variance of weighted residuals specified in subsection (15) for the set of test trees (), an upper one‑tailed F‑Test must be applied in accordance with subsection (17).
 (17) For the upper one-tailed F-Test:
 (a) an F-Test statistic must be calculated as the ratio of  on ; and
 (b) the F-Test statistic must be compared to a critical F-value  to determine if there is a statistically significant difference () between  and ; and
 (c) for the comparison, the numerator degrees of freedom and the denominator degrees of freedom are  and , where:
 (i)  is the number of test trees used to validate the allometric function, as a whole number; and
 (ii)  is the number of biomass sample trees used to develop the allometric function, as a whole number; and
 (iii)  is the number of parameters in the allometric function, as a whole number.
 (18) If the F‑Test statistic is less than or equal to the comparison critical F‑value, then the allometric function:
 (a) is taken to have been validated for application in that stratum; and
 (b) may be applied to all project trees of the relevant tree type occurring within the stratum that fall within the allometric domain of the validated allometric function.
 (19) If the F‑Test statistic is more than the comparison critical F‑value, the stratum is considered to fall outside the allometric domain of the allometric function.
 (20) In the case where subsection (19) applies, the project proponent may:
 (a) seek to validate an alternative existing regional function by undertaking the process specified in this section; or
 (b) for the project trees to which the allometric function was intended to be applied—count all occurrences of the relevant tree type in plots in the stratum as having zero carbon stock; or
 (c) develop a stratum specific function using the approach specified in section 68.
 (21) For paragraph (20)(c),
