Cox proportional hazard model is one of the most celebrated models for analyzing lifetime data. There exists one problem when we replace the covariate effects with varying-coefficient functions. That is whether this replacement is reasonable or partially reasonable. In this paper, we propose a hypothesis testing based on the asymptotic distribution of the normalized maximum deviations, for this problem,...
3D equipment operation simulation training system (3D-EOSTS) for solving difficult training problem is presented. System building based on 3D modeling can greatly improve the efficiency for the trooppsilas daily training. According to the equipment training requirement, the system architecture and functions are put forward. The whole system includes six simulators such as network simulator, headquarters...
A new stochastic stock price model of stock markets based on the contact process of the interacting particle systems is presented in this paper, where the contact model is a continuous time Markov process, one interpretation of this model is as a model for the spread of an infection. Through this model, the statistical properties of Shanghai stock exchange (SSE) composite index are studied. In the...
The statistical analysis of Chinese stock market fluctuations modeled by the interacting particle systems has been done in this paper. The contact process of the interacting particle systems is presented in this paper, where it is a continuous time Markov process, one interpretation of this model is as a model for the spread of an infection. Based on the contact process, a new stochastic stock price...
Linear auto-regression moving average with extra input (ARMAX) model for air temperature system in a naturally ventilated greenhouse was developed. Outside air temperature, relative humidity, global solar radiation and wind speed were used as disturbing input variables of the model, while inside temperature was used as output variable of the model. Based on energy and mass flows equations, statistic...
