毕业论文 概率统计模型在企业经济中的应用 概率统计模型在企业经济中的应用 摘 要 随着经济全球化，社会发展，科技进步，经济迅速发展，数学对于经济学的渗透 日益广泛?在经济分析中概率与数理统计的应用也变得日益广泛?国内外的经济学界和 经济部门更加意识到以概率与数理统计来解决经济问题的重要性及优越性?然而，实践 已证明，概率统计是对经济问题进行量的研究的有效工具，为经济预测和经济决策提供 了新的手段，这也有助于提高管理水平和经济效益. 同样，经济的多元化，也使企业面临的经济问题日益严峻?木文首先对概率统计进 行简单的总结，然后就针对现实生活中企业面临的不同经济问题，采用一元线性回归、 主成分分析法、决策树等概率模型逐一进行分析解决，以达到使金业规避风险，提高竞 争力并从屮获取最大收益的口的. 关键词：概率与数理统计，-?元线性回归，主成分分析法，决策树 Application of probability and statistics model in enterprise in the economy Author: Fu Keqing Tutor: Liu Wanli Abstract With the globalization of economy, social development, the progress of science and technology, the rapid development of economy, mathematics foreconomics increasingly widespread infiltration in economic analysis.Application of probability and statistics has become increasingly widespread.Economists at home and abroad and sectors of the economy to be more aware of the importance and superiority to solve economic problems inprobability and mathematical statistics. However practice has proved,probability and statistics, is an effective tool for quantitative research on economic issues, provides a new means for economic forecasting and economic decision-making, it also helps to improve the management level and economic benefits Similarly, diversified economy, but also to the economic problems facing enteiprises increasingly serious article first brief summary of probability and statistics, and then for different real-life economic issues facing businesses, using linear regression, principal component analysis, probabilistic models such as decision tree analysis to solve one by one, in order to achieve the enterprise to avoid risks, improve competitiveness and to derive maximum benefit purposes.
