本文对于非线性非高斯问题，提出了一种改进扩展卡尔曼滤波（NIEKF）新方法。该方法将迭代滤波理论引入到扩展卡尔曼滤波器方法中，有效地重复利用新的测量信息，还利用Levenberg-Marquardt 方法调整预测协方差阵以保证算法具有全局收敛性。实验结果表明，所提方法具有更高的估计精度，是一种效率较高、性能较好的跟踪方法。(This non-Gaussian for nonlinear problems, an improved extended Kalman filter (NIEKF) the new method. The method of iterative filtering theory is introduced to the extended Kalman filter method, the effective measurement of repeated use of the new information, also using Levenberg-Marquardt method to adjust the covariance matrix of prediction algorithm to ensure global convergence. Experimental results show that the proposed method has higher estimation accuracy, is a high efficiency, good performance tracking methods.)

该文研究了河南省不同年龄组的历史发展趋势和65岁以上人口未来发展趋势以及影响老龄化相关因素的问题。通过对不同时期的人口数据的分析和预测，从一个经典的模型入手，建立了三个不同的模型，分别 模型、 模型和关联分析模型，然后采用统计分析的方法来解决这些问题，预测出了河南省未来老龄化人口的发展。(This paper studies the different age groups in Henan Province of historical development trends and population over the age of 65, as well as the impact of future development trend of aging-related factors. Different stages of the analysis of population data and projections from a model of the classic, the establishment of three different models, namely, model, models and associated analysis model, and then using statistical analysis methods to solve these problems, predict the Henan Province, the future development of an aging population.)
