陈老师您好,看了您的《高级计量经济学及STATA应用》,里面提到了关于半参数回归,我在stata里找到了命令语句,semipar
具体格式为: Robinson's (1988) semiparametric regression estimator
semipar varlist [if] [in] [weight], nonpar(varname) [options]
nonpar(varname) Specifies the variable that enters the model nonlinearly
generate(varname) Generate the nonparametric fit of the dependent variable
我的问题是:基本语句结构是semipar y x1 x2 x3, nonpar(??)吗?
如果是,nonpar(??)里是什么变量?
解释中说, nonpar(varname) Specifies the variable that enters the model nonlinearly。是什么意思啊?
谢谢陈老师
