replace x = y if x == 1 // 正确的赋值和比较操作符使用 重新运行修正后的代码,验证是否解决invalid syntax问题: 在修正代码后,重新运行程序,检查是否还会出现“invalid syntax”错误。 如果问题仍未解决,查阅Stata官方文档或社区寻求帮助: 如果经过上述步骤后问题仍然存在,可以查阅Stata官方文档,了解更多的语...
save test3, replace log close log1 宏的知识较多,以后再另写推文 1.循环 1.1 while while evaluates exp and, if it is true (nonzero), executes the stata commands enclosed in the braces. It then repeats the process until exp evaluates to false (zero). while 是依据表达式的真假进行循环,后面...

则键入命令: g y=0 if year==2006 replace y= 1 if year==2007 7 、 内存管理当打开一个数据文件时 , Stata读取后会将其载入内存 。能否读入内存取决于内存空间和数据文件的容量大小 。一般 情况下 , Stata10版本中缺省内存空间一般是10MB,如果数据文件容量超过了缺省内存设定的空间 , 比如要打开的数据...
