具有随机多次抽取和随机加法的瓮模型

Urn models with random multiple drawing and random addition

Irene Crimaldi, Pierre-Yves Louis, Ida Germana Minelli

摘要:

考虑了一个具有多重抽取和随机时变加法矩阵的瓮模型。该模型是非常普遍的相对于以前的文献:在每个时间步的采样球的数量是随机的,添加矩阵具有一般的随机元素。对于给定颜色的球的比例,我们证明了几乎必然收敛结果和波动定理(通过CLT在稳定收敛和几乎必然条件收敛的意义下,这是强于依分布收敛)。给出了分布一般未知的极限比例的渐近置信区间。

英文摘要:

We consider an urn model with multiple drawing and random time-dependent addition matrix. The model is very general with respect to previous literature: the number of sampled balls at each time-step is random, the addition matrix has general random entries. For the proportion of balls of a given color, we prove almost sure convergence results and fluctuation theorems (through CLTs in the sense of stable convergence and of almost sure conditional convergence, which are stronger than convergence in distribution). Asymptotic confidence intervals are given for the limit proportion, whose distribution is generally unknown.
