摘要: 设{Xnn≥1}为严平稳的φ-混合序列,{Nnn≥1}为一列非负整值随机变量序列,且与{Xnn≥1} 独立,随机部分和为SNn=Xi,在适当的假设条件下,利用φ混合序列的极限性质,证明了严平稳φ混合序列的随机中心极限定理,得到了Xn=(SNn-ESNn)/√VarSNn))依分布收敛于TZ1Z2),其中TZ1Z2)为Z1Z2的线性函数,Z1N(0,1),Z2为{Nnn≥1}正则化后的极限分布.

Abstract: Let {Xn,n ≥ 1} be a strictly stationary φ-mixing sequence, {Nn,n ≥ 1} be a sequence of nonnegative integer valued random variable. Note SNn=Xi be the random partial sums, we prove the random central limit theorem for strictly stationary φ-mixing sequence using the limit properties of φ-mixing sequence under some suitable conditions, and obtain that Xn=(SNn-ESNn)/√(Var(SNn)) converges to T(Z1,Z2), where T(Z1,Z2) is the linear function of Z1 and Z2, Z1~N(0,1), Z2 is the limit distribution after normalization of Nn,n ≥ 1.
Key words: φ-mixing sequence    random partial sums    random central limit theorem
