z-vars是包含感兴趣的控制变量名称的变量列表。 Factor variables允许使用因子变量。z变量的因子变量只允许在Stata 12或更高版本中使用。如果指定了option -xstandard-,则不允许key-vars使用因子变量。如果在指定的模型类型中允许,则允许使用aweights, fweights, iweights, and pweights Concomitant(varlist)指定控制变...
在Stata中遇到“string variables may not be used as factor variables”这一错误时,通常意味着你尝试将字符串类型的变量用作因子变量,但Stata不支持这样做。为了解决这个问题,你可以按照以下步骤操作: 理解错误原因: 这个错误表明你尝试在回归分析或类似需要使用因子变量的命令中使用了字符串类型的变量。Stata要求因...
