Synopsis

数据支持与管理的SAS编程技术及实现案例———基于计算机辅助调查模式基于笔者多年从事SAS软件教学及参与综合性社会调查项目数据处理实践的经验,首先阐述计算机辅助调查模式下综合性调查项目对数据管理和数据支持的需求,然后梳理常用的实现数据管理与数据支持任务的SAS过程、语句及其功能,重点从实际应用出发,基于中国家庭动态跟踪调查项目真实和复杂的实践情境,结合12个典型SAS编程案例,分别从数据需求、难点分析、解决思路、具体SAS实现程序以及程序编写技巧等角度进行详细解析,探讨实现综合性调查项目数据管理与数据支持实时化、规范化和高效化的SAS编程技术。第1章计算机辅助调查概述1.1计算机辅助调查技术的产生及其发展随着计算机技术的出现和逐步成熟,计算机辅助调查的理念和技术出现了。计算机辅助调查是指在问卷调查过程中,将传统的调查方式与计算机相结合,完成数据的搜集、录入与整理等工作,工作形式通常为通过电脑屏幕展现问题,由访问者或被访者依据交互式的电脑程序所呈现出的特定规则的问题,通过计算机直接录入答案。计算机辅助调查技术发源于欧美。电话调查在美国发展较早,20世纪70年代美国市场研究领域就出现了计算机辅助电话调查(computerasistedtelephoneinterviewing,CATI)系统,而CAPI技术则是20世纪80年代率先在欧洲出现。1.2计算机辅助调查系统的特点与传统的数据搜集方法相比较,计算机辅助调查系统的特点是以应用计算机为主,把传统的统计工作步骤,包括从数据搜集、录入到数据编辑,都在调查员的个人电脑上来完成,在回答者、调查者与数据用户之间形成一个有机结合的相互作用的循环。相比于传统的纸笔访问,基于计算机辅助调查系统的采访模式具有以下明显优势。(1)可以有效避免因问题跳转而选错路径所导致的错误。在计算机辅助调查模式下,借助于计算机程序设定的逻辑判断语句,对于有跳转的选项问题,通过恰当的逻辑关系设定,由计算机程序引导访员和被访者,依据前面回答的结果,由计算机程序来判断下面应出现什么问题,同时不需要被特定被访者回答的问题也可以自动跳过,从而避免因路径选择错误而造成漏题或错答等情况。因此,自动路径控制可以大大减少无效数据的数量。(2)可以实现对所获取调查信息的同步有效性检验。在传统面访中,有效性检验通常只能在数据搜集后的数据审核阶段进行,这时即使发现错误,也只能进行有限的事后弥补,因为重新找到当时的被访者再进行验证和调查几乎不具有可操作性。在计算机辅助调查模式下,设计调查问卷时,可以事先对每一个问题设定允许的值域范围,甚至还可以进行更为复杂的多个答案相关联的有效性判断。数据采集过程中,系统会自动校验采集到的信息是否在允许的范围或者是否符合逻辑关系检验。当检查结果与设定逻辑不一致时,系统会出现校验提示。根据校验提示强度的不同,可分为强制性校验(hardcheck)和提示性校验(softcheck)两种。其中,提示性校验更多地被运用于校验单一问题答案的异常情况。当提示性校验出现时,访员可以根据实际情况选择“强制通过”、“关闭修改当前答案”、“修改相关题目答案”三种操作模式。(3)可以提供更加生动的表现方式。在计算机辅
