多元线性回归分析是一种重要的数据处理方法, 借助图形化的虚拟仪器开发平台LabVIEW 可开发出集数据剔错、模 型构建、统计检验、区间估计与预测等功能为一体的多元线性回归的可视化数据处理系统。系统构建方法新颖和稳健, 通用 性和适应性强, 可方便地与数据采集整合使用, 又可单独应用, 具有广泛应用价值。文章对系统的构建与设计作了阐述, 给 出了主要的实现程序。-Abstr act:The multivariate linear regression analysis is an important data processing method. The visual data processing system of the multivariate linear regression has been developed by using graphic virtual instrument engineering workbench- LabVIEW, which collects the functions of inordinate data elimination, model constructing, statistic test, interval estimate and prediction. The constructing method of the system is new and sane, and its versatility and adaptability are good. The software can be integrated with the data acquisition conveniently, and can also be applied alone and it is of extensive application value. The article describes the construction and the design of the system and gives the main realizing program. Key words:LabVIEW, multivar iate linear r egr ession, data proces
