简单随机抽样
simple random sampling
- 摘要提出基于重排序集抽样的符号检验，给出相应的极限分布，并讨论了相对于基于简单随机抽样和排序集抽样的符号检验统计量的渐近效率，得出此检验具有较高的功效。
A new sign test based on double-ranked set sampling is proposed, and its asymptotic distribution was obtained; And the asymptotic efficiency relative to under SRS and RSS was discussed, which show that this test had higher efficiency. - 这课程研究如何用乱数并透过随意抽样、随机选择证物、破坏对称以及马可夫链使得演算法更简单和更有效率。
This course examines how randomization can be used to make algorithms simpler and more efficient via random sampling, random selection of witnesses, symmetry breaking, and Markov chains.
