摘要:
本文证明了改进后的对称分布期望估计量W_p在一定条件下具有无偏性和强相合性,并给出了方差的上界,其中:W_p.=1/n-2[np] sum from a-[ap] to i=[ap]+1 X_(j),0≤p
Abstract:
This article proves that the improved symmetrical distribution is expected to measure W_P under certain conditions, which is unjustified and strong, and gives the upper bounds with a variance.
