Based on correlation analysis on dispatching object and control measures, further research is made on regression analysis statistic of confidence regions based upon control matrix, and a sufficient condition is given for the control matrix to achieve a better regression estimation, which has some guidance significance to the optimization of multi-object dispatching.

Smooth empirical likelihood to construct the confidence region of censor quantile regression model under independent and identically distribution samples is discussed.

A numerical method of the verification of μ=μ_0 and the confidence regions of μ when knowing of ∑;

The result is then used to construct confidence regions of the parameter vector in the EV linear regression models with asymptotically correct coverage probabilities.

The coverage errors of the constrained empirical likelihood confidence regions for means are of order n -1 .

By the discussion of parametric variation region under the condition of stability null solution for two-dimension overlay linear differential systems, we obtain some theorems to tell us how to get the parametric variation region of n -dimension linear or nonlinear autonomous differential systems that the null solution is stable.

The approach to develop a ground motion attenuation relation in a country or region with no enough observed data is deal with by means of seismological method in this paper, and mainly on the estimation of regional parameters.
