优惠券收集器问题中的k吨数

The number of k-tons in the coupon collector problem

J. C. Saunders

摘要:

考虑优惠券收集者问题,其中每盒一种品牌的谷物包含一张优惠券,并且有n种不同类型的优惠券。假设一个盒子中包含特定类型优惠券的概率是$1/n$,我们继续购买盒子,直到我们至少收集到每种类型的$m$优惠券。对于$k\geq m$,如果我们看到某张优惠券的$k$倍,那么我们就称之为$k$ -ton,因为我们已经看到了所有优惠券的$m$副本。在这里,我们确定的渐近分布后,我们已经收集了$m$副本的每个优惠券的任何$k$在一个有限的范围内,给定任何固定的$m$。我们还确定了渐近联合概率分布在这样的值的$k$和总数量的优惠券收集。

英文摘要:

Consider the coupon collector problem where each box of a brand of cereal contains a coupon and there are n different types of coupons. Suppose that the probability of a box containing a coupon of a specific type is $1/n$ and that we keep buying boxes until we collect at least $m$ coupons of each type. For $k\geq m$ call a certain coupon a $k$-ton if we see it $k$ times by the time we have seen $m$ copies of all of the coupons. Here we determine the asymptotic distribution of the number of $k$-tons after we have collected $m$ copies of each coupon for any $k$ in a restricted range, given any fixed $m$. We also determine the asymptotic joint probability distribution over such values of $k$ and the total number of coupons collected.
