The wavelet method used in economic forecast depends on its " mathematics microscope " property . it does the layer analysis and forecast to indicators . it can improve forecast precision , what ' s more it can search and express the structural feature of data such as development cycle , second cycle , especially to some sudden change data which will provide effective and reliable warranty to the complexity and violent fluctuant data indicators in enterprise 基于小波进行经济预测的方法依靠其“数学显微镜”的特性，对待分析的预测指标进行逐层分析和预测，在提高预测精度的基础上，能对分析数据对象的结构特征进行挖掘，分析数据特征如发展主周期、次周期等，尤其对具有突变性质的数据具有很好的表征分析能力，这对于企业中复杂的变动剧烈的数据指标的预测能提供有效可靠的保证。
Based on artificial neural network technique , a regional economic forecasting system , which has been applied to practical regional medium - and long - term economic forecasting in certain city , is designed . a mixed hs - fr conjugate gradient algorithm is applied to the regional economic forecasting system to train the neural networks effectively 将人工神经网络技术应用于地区经济预测领域，设计了一个“基于人工神经网络的地区经济预测系统” ，并利用hs - fr共轭梯度算法对网络的学习算法进行了改进。
This paper mainly deals with the multivariate bayesian inference theory used in the modern economical and management science . this includes the bayesian inference theory about three important kinds of linear models , including the single equation model , multiple equation model system and var ( p ) predictive model , and their application in economic forecasting and quality control , and also the design for the bayesian classification identification method among multiple populations 本文主要研究现代经济管理中的多元贝叶斯推断理论，包括单方程模型、多方程模型系统和向量自回归var ( p )模型的贝叶斯推断理论及其在经济预测与质量控制中的应用，以及多总体的贝叶斯分类识别方法的构造。

In these rather gloomy times , an optimistic medium - range economic forecast , a few creative ideas for reforming the civil service and the financial markets , the disneyland project , the cyberport and the intended public listing of the mtrc have all given new hope to the people of hong kong . the 8 . 5 billion tax rebates is a further shot in the arm to alleviate the pain of financial sufferings of millions of citizens 较乐观的中期经济预测，大刀阔斧的公务员及金融体制改革建议，迪士尼乐园数码港地铁上市等充满活力和机遇的计划，为近期感觉前景黯淡的市民燃点起希望8 5亿退税措施更带来骤然的意外惊喜，减轻了百万市民手紧之苦。
Integrated with domestic and foreign economical theory that people have obtained common consensus , mainly based on data in yearbook of china transportation & communications , making use of exploratory data analysis method and factor analysis method etc . , the dissertation aims to find out the law and tendency of communications and transportation ' s development , make economic forecasting , test reliability and feasibility of all sorts of economical theory and recommend for all or different governments and enterprises 本论文主要从交通统计年鉴数据出发，结合国内外已取得共识的经济理沦，运用探索性数据分析和因子分析等方法，借以找出交通运输业发展的规律性及其发展趋势，用以作经济预测，检验各种经济理论的可靠性和可行性，并为各级政府和企业的经济决策提供数量化建议。
We left this birthday party somewhere between hope and despair and with the convection , not really newly acquired , that proper statistical methods applied to ascertainable facts have their merits in economic forecasting as long as neither forecaster nor public trends for a prediction of certainties of mathematical exactitude 我们离开了这喜忧参半的生日晚会，但也有那种由来已久的信心：将恰当的统计方法用于准确的具体材料，对于经济预测有很大的作用，但前提是预测者本人也好，公众也好，决不能把对可能性和趋势的估计错当成对有数学正确性的确凿事实的预测。
