回归变量 meaning in English

regressed variable
regression variable

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
这些方法本质上讲都是局部估计或局部光滑，当回归变量x为一维变量时，非参数回归函数用这些方法一般都能得到很好的估计。
But the multivariable nonparametric regression function could not be well estimated by the local estimator because there is o nly a little data in the local fields of the high dimension regression variable x . this phenomenon is said to be " the curse of dimension "
但当回归变量是多维向量时，由于x的局部邻域包含很少的数据，用这些估计方法，很难估计出一般的多元非参数回归函数，人们把这种现象称为‘维数祸根’ ( thecurseofdimension ) 。
