Stata新命令:超级强大的

全文阅读:.html

egen → egenmore → gtools

Stata 中的 egen 命令提供了大量的函数,能大幅提高数据处理效率。

随后由 Nicholas J. Cox 提供的 egenmore 进一步丰富了 egen 的函数库,在文字处理方面的功能大幅提高。

而今,由 Mauricio Caceres 编写的 gtools 命令组则在速度提升方面将上述工作向前推进了一大步。

让我们怀着崇高的敬意访问 「gtools 主页」。


下面是作者写的感言:


Hi! I'm Mauricio Caceres; I made gtools after some of my Stata jobs were taking literally days to run because of repeat calls to egencollapse, and similar on data with over 100M rows. Feedback and comments are welcome! I hope you find this package as useful as I do.

Along those lines, here are some other Stata projects I like:

  • ftools: The main inspiration for gtools. Not as fast, but it has a rich feature set; its mata API in particular is excellent.

  • reghdfe: The fastest way to run a regression with multiple fixed effects (as far as I know).

  • ivreghdfe: A combination of ivreg2 and reghdfe.

  • stata_kernel: A Stata kernel for Jupyter; extremely useful for interacting with Stata.
