查询词典 estimate for

A point estimate may be the researcher's best guess at the population value, but, by its nature, it provides no information about how close the estimate is "likely" to be to the population parameter.

点估计本身并不能告诉研究者该估计值和总体参数的距离到底有多近。

在抽样技术比例估计与均值估计的基础上，提出了抽样技术的比率估计法，并对其作了详细的分析，同时，通过具体问题的讨论，说明了比率估计法所具有的优越性；针对各个样本比值有比较大的差别时所产生的不稳定性，运用聚类分析的方法提出了具体的比率估计法的改进公式，减少了噪声数据的影响，得到了较高的准确度。

Therefore, when the grid technique or the district was applied to regionalize spatial scale, individual soil profile are needed more to reduce uncertainties of the estimate of soil organic matter in the grid or the district with spatial scale up, but the uncertainties are smaller when using soil organic matter content in wellestimate gird or district to estimate the grid or district without available data by extrapolation.

因此，采用网格法或行政区划分空间区域，获得空间区域单元内土壤有机质含量或贮量的精确估算需要较多的剖面，但外推至数据不足的空间区域时，估算的不确定较小；采用土壤分类单元为空间区域单元，结果则相反。
