1.1 数据标记label define+ label value Stata通常不直接标记某个变量为分类变量。在Stata的基础数据类型里面,除了日期型,就剩下字符串型和数值型。后两种变量类型刚好对应分类变量的两种表示方法。而且,这两种编码还可以通过取值标签(label define+value)对应起来。下面我们举一个最最简单的例子进行说明——假设我们有...
stata egen newid = group(id), label 这条命令会根据id变量的唯一值创建一个新的变量newid,其中每个唯一值都被映射到一个新的整数上(从1开始)。然后,你可以使用newid作为因子变量进行后续分析。 检查数据输入:确保在数据输入阶段没有引入非整数值或超出范围的整数值。这可以通过数据清洗和验证步骤来实现。 综上...
