You can combine args and incrementing through an unknown number of positional arguments. Say that you were writing a subroutine that was to receive varname, the name of some variable; n, which is some sort of count; and at least one and maybe 20 variable names. Perhaps you are to sum ...

Abstract: The wild bootstrap was originally developed for regression models with heteroskedasticity of unknown form. Over the past 30 years, it has been extended to models estimated by instrumental variables and maximum likelihood and to ones where the error terms are (perhaps multiway) clustered. ...

摘要:在本文中,我描述了一个由社区贡献的命令intcount,它适合几种以间隔形式观察到的计数数据的回归模型之一。可用的模型为Poisson,负二项式和二项式,它们可以标准或零膨胀形式拟合。我用一个应用程序来说明该命令,该应用程序用于分析英国理解协会关于医疗保健服务需求的调查数据。文章...
