type II error

Results The type ⅰ error and type ⅱ error estimate of 8 one way multiple sample tests are given.

结果给出了8种检验方法的Ⅰ型和Ⅱ型误差估计值。

Conclusion: How to select the method for multiple comparisons of rates in order to control the type ⅰ error or type ⅱ error is introduced.

结论：给出了控制Ⅰ型误差、Ⅱ型误差或误差3种不同情况下，多个实验组与对照组比较及多组间的两两比较方法的不同选择。

However, due to the limitations of data and methods, the model also has shortcomings, such as neglecting the difference between the sub-sectors in the transport sector, and neglecting the difference cost between the error type I and type ⅱ.

但是由于数据和方法的限制，该模型也有不足之处，如没有考虑交通运输业内子行业之间的差异，没有考虑第一类错误和第二类错误的成本问题等。

Then, a novel type ⅱ hybrid error control mode is proposed, the throughput performance is analysed, the result shows this mode can have higher throughput than current available ARQ mode via limited memory capacity and complexity.

之后，又提出了一种新的第2类混合差错控制方式，分析了其吞吐量性能，结果证明，此方式能以有限大的存储容量和实现复杂度达到比现有方式更高的吞吐量。
