Sinceβkernel is non-symmetric, there will be problem in the precision of graduation if using kernel graduation method, because, generally, kernel function is supposed to be symmetric in kernel graduation method, thus will cause boundary deviation in actual application.

但β核为非对称核，如果使用核修匀方法，在修匀精度上仍会存在问题，因为一般核修匀方法中均假设核函数具有对称性，在实际应用中将导致出现边界偏差现象。

Symmetric kernel graduation ; non-symmetric kernel graduation ; Gamma kernel ; boundary bias

对称核修匀；非对称核修匀； Gamma核；边界偏差
