让 { X, X n, n ≥ 1 } 是严格地静止的 φ-mixing 的一个序列在正常法律的吸引力的域的积极随机的变量。在一些合适的条件下面,为部分和的自我使正常化的产品的弱不变性原则被获得。
Let variables in the {X, Xn, n ≥ 1} be a sequence of strictly stationary φ-mixing positive random domain of attraction of the normal law. Under some suitable conditions the principle for self-normalized products of partial sums is obtained.
