摘要 具有单位方差的中心化平稳高斯三角阵{X_(i,n),1≤i≤n},在其相关系数ρ_(j,n)=E(X_(i,n)X_(i+j,n))满足文献[14]的条件下,本文证明了该高斯三角阵的聚集点过程依分布收敛于泊松过程,并且聚集点过程与该高斯三角阵的部分和渐近独立. Let[X_(i,n),1≤i≤n]be a centered stationary Gaussian triangular array with unit variance.Assuming the correlation pj,n=E(X_(i,n) X_(i+j,n))satisfies the conditions in[14],this paper is interested in the joint behavior of the point process of clusters and the partial sum of the Gaussian triangular array.It is shown that the point process of clusters converges in distribution to a Poisson process and is asymptotically independent with the partial sums.
