1.
By two-stage procedures,the paper designs a Tukey two-stage simultane- ous confidence interval of prescribed reliability (confidence level) and prescribed precision (the width of the interval) and provides the optimal sample size of the first stage by numerical computations.
且利用数值计算的方法给出了第一阶段最优抽样量。
2.

5) sampling algorithm
抽样算法
1.
Furthermore, in terms of the character to composite the posteriors distribution,the paper design sampling algorithm for the conditional posteriors distribution of mean and covariance-matrix in normal distribution with monotone missing data configuration.

补充资料:最优抽样比
分子式:
CAS号:
性质:抽样误差最小而抽样经费开支最省的抽取比。抽样误差随抽样数的增加而减小,而经费开支随抽样数增加而增加,两者是相互制约的。在实施抽样时,通常很难同时满足这两个条件,合理的做法是,在给定的经费条件下使抽样误差最小,或者,在给定抽样误差的条件下使抽样费用最省。
