对于当前使用双重抽样进行分层并减少第二阶段样本量的清单,与之前的清单相比,我们开发了一个三阶段抽样程序,该程序利用之前清单的绘图数据或其基于增长模型的更新来提高精度。三相程序将分层的双采样与层内的两相回归估计器相结合。我们考虑在第一阶段从无限总体中进行抽样。使用德国下萨克森州四个国家林区两次连续清查的数据,在案例研究中对组合估计器进行了测试。来自第二次的减少数量的样地的数据与(1)来自第一次的体积或(2)来自第一次的样地的生长模拟相结合。来自先前清单或其更新的数据充当目标变量的分层均值回归估计器的辅助变量。该案例研究表明,在使用两种类型的辅助变量的定期库存设计中,精度显着提高,因此在减少中间库存方面具有巨大的成本节约潜力。
For a current inventory using double sampling for stratification with a reduced second-phase sample size, compared with a previous inventory, we develop a three-phase sampling procedure that exploits plot data from the previous inventory or their updates based on a growth model to increase precision. The three-phase procedure combines double sampling for stratification with a two-phase regression estimator within strata. We consider sampling from an infinite population in the first phase. The combined estimator is tested in a case study using data from two consecutive inventories in four State Forest Districts in Lower Saxony, Germany. Data from a reduced number of sample plots from the second occasion are combined with (1) volumes from the first occasion or (2) growth simulations on the sample plots from the first occasion. The data from the previous inventory or their updates serve as the auxiliary variable for the regression estimator of the strata means of the target variable. This case study indicates a remarkable increase in precision and thereby an enormous cost-saving potential for reduced intermediate inventories in a periodic inventory design with both types of auxiliary variables.
