SAS(Statistical Analysis System)是由美国北卡罗来纳州立大学于1966年开发的用于管理数据和编写报告的统计分析软件系统(最初用于大型机上,1986年推出微机版本),经过多年来的完善和发展,SAS系统在国际上已被誉为统计分析的标准软件,现已在各个领域中(包括农牧科研、教学及生产单位)得到了广泛的应用.SAS系统是一个功能非常齐全、应用极广、适用性很强、使用灵活、易于操作、模块化的综合软件系统.它有以下几个特点:全面的管理数据、灵活的用户界面、集成化的计算环境、完整的应用系统.它可完成各个统计过程:如T—检验、方差分析、相关与回归、多元统计分析等.下面以一个随机区组(单位组)设计资料的方差分析(二因素一元方差分析)在畜牧饲养试验结果分析中的具体应用实例,谈谈我们编写SAS程序以实现标准软件电算化的体会.
SAS (Statistical Analysis System) is a statistical analysis software system developed by North Carolina State University in 1966 for data management and report writing (originally used on mainframes and computer version released in 1986). After years of improvement and Development, SAS system has been praised as the standard software for statistical analysis in the world and has been widely used in various fields (including scientific research, teaching and production units) .SAS system is a complete function, Wide applicability, flexible, easy to operate, modular integrated software system. It has the following characteristics: a comprehensive management of data, flexible user interface, integrated computing environment, a complete application system. It can Complete the statistical process: such as T-test, analysis of variance, correlation and regression, multivariate statistical analysis, etc. Below a random block (unit group) analysis of variance analysis of the design data (two-factor univariate analysis of variance) In the specific application examples, talk about our SAS program written to achieve the standardization of computerized experience.
