灯泡过程的棒状二项式近似

Clubbed Binomial Approximation for the Lightbulb Process

Larry Goldstein, Aihua Xia

摘要:

在所谓的灯泡过程中,在r=1,...,在N个灯泡中,所有最初关闭的、恰好R个灯泡被均匀地选择并且独立于过去,它们的状态从关闭改变为打开,或者反之亦然。当W_n为终末时间n时的鳞茎数,C_n为适当的棒状二项分布时,d_{TV}(W_n,C_n)\le 2.7314 \sqrt{n} e^{-(n+1)/3},对于所有n \ge 1。用Stein方法给出了结果。

英文摘要:

In the so called lightbulb process, on days r=1,..,n, out of n lightbulbs, all initially off, exactly r bulbs selected uniformly and independent of the past have their status changed from off to on, or vice versa. With W_n the number of bulbs on at the terminal time n and C_n a suitable clubbed binomial distribution, d_{TV}(W_n,C_n) \le 2.7314 \sqrt{n} e^{-(n+1)/3} for all n \ge 1. The result is shown using Stein's method.
