We introduce the general sigma point selection framework, and give two kinds of efficient methods: a reducing the computing complexity by decreasing the number of the sigma point; b scaling the sigma points to influence the effects of the higher order moments, then improve the accuracy of the UT; c Convergence analysis of the UKF, when used as an observer for nonlinear deterministic discrete-time system, is presented. Based on the UKF that captures the posterior mean and covariance accurately to the second or third order term (in terms of Taylor series expansion) for any form of nonlinearity, sufficient conditions to ensure local asymptotic convergence are established.

From the microcosmic structure of securities market,the problems of stock market liquidity and bargain amount change were analyzed. The dispersed model of amount dynamic state of bargainers was discussed. By neglecting price change,an appropriate proportion of bargainer quantity of both buyer and seller is the lowest standard of the market liquidity. The time achieving stable market liquidity has relation to parameters for bargainer to leave the stock market. Finally,simulation calculation of bargainer quan...
