Cut-off importance sampling of bole volume.
Cut-off importance sampling (CIS) is introduced as a means of sampling individual trees for the purpose of estimating bole volume. The novel feature of this variant of importance sampling is the establishment on the bole of a cut-off height, H, above which sampling is precluded. An estima...
