New method increases computational efficiency, and deletes correlativity of new scalar coefficient estimators of quasi regression. When samples size is very large, it has the same accuracy as quasi regression An and Owen (2001) does.

• 新方法不仅具有很高的计算效率 ；而且标度参数的估计量之间不再具有相关性 ；当样本容量很大的时候 ；新方法能够达到原方法 (文献 [1 ]；An and Owen的方法 )的计算精度 .
