摘要:

A method is proposed for adjusting small-sample-based stock and stand table entries from point, double sampling with a ratio of means estimator. The proposed adjustment uses the characteristics of the ratio of means estimator, ensures that totals from the stock and stand tables match the large sample estimates, and preserves the volume–basal area ratio by DBH class before and after adjustment. Bias and variance estimates for the adjusted stock table entries are presented.
