摘要
鉴于分段拟合技术在国内外数量预测技术中还很少见,本文利用现代统计分析软件SPSS13.0着重考虑这一特殊数据处理技术,结合中铁一局的实际数据,对这一问题做了全面的研究,通过对该局26年的工程任务年完成工作量进行了纯技术性的分段拟合并与单一的拟合结果作了对照,得到对这一企业的拟合应当采用分段函数建立更贴近实际的预测模型。目的在于推广这一技术方法的进一步应用,借以提高科研项目和科技论文的技术质量。
In view of the fact that the partition fitting technology is also very rare in the domestic and foreign quantity forecasting technology, this article uses modern statistical analysis software SPSS13.0 to consider emphatically this special data technology,in the union a hard game of actual data, has done the comprehensive research to this question, through has carried on the merely technical partition fitting to this game of 26 year project duty year fulfil working quotas and has made the comparison with the sole fitting result, obtains must use the partition function establishment to this enterprise＇s fitting to draw close to the actual forecast model. The goal lies in promotes this computing technique the further application, in order to enhances the scientific research item and the technical paper technical quality.
