Asymptotic Approximations for Distributions of Ratios of Linear Functions of Random Variables
随机变量线性函数之比的分布渐近近似
Summary Normal asymptotic approximations for the distribution of the ratio of linear functions of independent and identically distributed random variables are derived. These approximations are checked for accuracy by comparisons with exact known distributions in specific examples. In particular, the examples considered are the distribution of the circular serial correlation coefficient and Watson's distribution. The comparisons suggest that for sample sizes as small as 10 or…
