解釋
協變量-
Three evaluation methods for the nonrandomized precipitation enhancement operation effects have been developed based on the regional rainfall control and meteorologit cal covariable correlation : dopple ratio analysis evaluation method using regional rainfall ten - dency control for single cloud seeding operation case ; regression analysis evaluation effects on the bases of regional correlation and developing tendency of rainfall ; and multiple regression analysis with meteorological and physical covariables
本文根據區域趨勢控制和氣象-物理協變量相關設計了三套非隨機化人工增雨作業效果評估方案：個例作業區域趨勢對比雙比分析評估方案、區域趨勢相關回歸分析評估方案和氣象-物理協變量多元回歸分析評估方案。 -
The essence of the above estimating methods is local estimator or local smoothing technique. in general, the non - parametric regression function is. well estimated by the above methods when the covariable x is one dimension
這些方法本質上講都是局部估計或局部光滑，當回歸變量x為一維變量時，非參數回歸函數用這些方法一般都能得到很好的估計。
