动态因子模型，该模型可以有效对高维数据进行降维，将成百上千的数据信息浓缩在几个因子里面，即从一国许多经济时间序列数据中估计和解释驱动各变量波动的共同动态因子。 MATLAB代码(dynamic factor model, the model can be effective for high-dimensional data dimension reduction, condensed the hundreds of thousands of data in several factors, that is, from a country many economic time series data in the estimation and explain the common dynamic factors drive the variable volatility.MATLABcode)

说明：  GPS噪音的matlab仿真的一个例子，结果正确。(GPS noise matlab simulation of an example of the results correctly.)

非静止多波束声呐混响的自回归模型。综合考虑了环境，几何结构等多种因素通过时变自相关函数仿真混响复数据序列。(This work describes a technique for simulating nonsta- tiouary multibeam Gaussian sonar reverberation sequences. The primary objective is to simulate quadrature-demodulated complex digital vector sequences that have a prescribed time-variaut Covariance function. )
