serial correlation
2.Controlling time-specific and province-specific factors and serial correlation, we find there is conditional convergence of regional disparity for province-based rural development and internal disparity among the East, the Middle and the West of China.
3.This paper makes tests of weak-form efficiency for SSE A Share Composite Index,SZSE A Share Component Index,Dow Jones Industrial Average and NASDAQ Composite Index by means of serial auto-correlation,run test,filter rule and auto-regression.
4.The principle of a parallel-serial fast acquisition spread spectrum system was brought forward, the average acquisition time of this method was compared with that of gliding correlation and verified with simulations , and a scheme for its implementation based on VHDL was presented.
