多到达随机抽样条件下的息票收集者问题的注记

A note on the coupon - collector's problem with multiple arrivals and the random sampling

Marco Ferrante, Nadia Frigo

摘要:

在本说明中,我们评估的预期等待时间,以完成收集的优惠券,在这种情况下的优惠券到达组的大小不变,独立和不平等的概率。作为一个应用,我们将能够确定期望的g维样本样本个数,为了观察给定种群中的所有类型的个体,我们必须独立地抽取这些样本。

英文摘要:

In this note we evaluate the expected waiting time to complete a collection of coupons, in the case of coupons which arrives in groups of constant size, independently and with unequal probabilities. As an application we will be able to determine the expected number of samples of dimension g that we have to draw independently in order to observe all the types of individuals in a given population.
