阶梯历元的局部极限定理
Local limit theorems for ladder epochs
摘要:
设{S_n,n= 0,1,2,.}是由i.i.d.序列产生的随机游动。随机变量X_1,X_2,.设τ为第一个下降阶梯时期。假设X_1的分布属于α-稳定律的吸引区域,我们研究了P(tau=n)的渐近行为。
英文摘要:
Let {S_n, n=0,1,2,...} be a random walk generated by a sequence of i.i.d. random variables X_1, X_2,... and let tau be the first descending ladder epoch. Assuming that the distribution of X_1 belongs to the domain of attraction of an alpha-stable law, we study the asymptotic behavior of P(tau=n).
