To download either program, simply type the following command once in Stata (replacing program_name with FELSDVREG or REGHDFE): ssc install program_name This command will load everything associated with programs, including the help files. reghdfe is a Stata package that estimates linear regressions with multiple levels of fixed effects. Introduction to implementing fixed effects models in Stata. stata最新命令reghdfe的下载安装方法,当模型中的固定效应数目较多时，stata的运算速度非常缓慢，有时候一两个小时也难以跑出结果。reghdfe命令恰好能解决这一问题。但也发现有些版本的stata并不能直接安装，因此，楼主在附件中提供了reghdfe命令两个version 的下载安装方法。 Previously, reghdfe standardized the data, partialled it out, unstandardized it, and solved the least squares problem. REGHDFE: Linear and IV/GMM Regressions With Many Fixed Effects. It’s objectives are similar to the R package lfe by Simen Gaure and to the Julia package FixedEffectModels by Matthieu Gomez (beta). It now runs the solver on the standardized data, which preserves numerical accuracy on datasets with extreme combinations of values. However users can still install these files to their U drive. 28 6270.3 saswrapper Dan Blanchette. It works as a generalization of the built-in areg, xtreg,fe and xtivreg,fe regression commands. As seen in the benchmark do-file (ran with Stata 13 on a laptop), on a dataset of 100,000 obs., areg takes 2 seconds., xtreg_fe takes 2.5s, and the new version of reghdfe takes 0.4s Without clusters, the only difference is that -areg- takes 0.25s which makes it faster but still in the same ballpark as -reghdfe-. reghdfe is a Stata package that estimates linear regressions with multiple levels of fixed effects. To install the estout package, type . ssc install estout, replace in Stata. First, from within Stata you can issue the command “sysdir” to see the list of the system set directories, to which Stata points to by default. "IVREGHDFE: Stata module for extended instrumental variable regressions with multiple levels of fixed effects," Statistical Software Components S458530, Boston College Department of Economics.Handle: RePEc:boc:bocode:s458530 Note: This module should be installed from within Stata by typing "ssc install ivreghdfe". It's objectives are similar to the R package lfe by Simen Gaure and to the Julia package FixedEffectModels by Matthieu Gomez (beta). 27 6313.7 reghdfe Sergio Correia. Installation Installation using the ssc command (recommended). REGHDFE: Linear and IV/GMM Regressions With Many Fixed Effects. It works as a generalization of the built-in areg, xtreg,fe and xtivreg,fe regression commands. The gitget command - which is a wrapper for github install - can install or update Stata packages from GitHub only by asking the package name: gitget packagename [, stable version("")] For example, if you wish to install markdoc package, typing gitget markdoc would be as goo as typing github install haghish/markdoc. 29 5294.5 ranktest Mark E Schaffer, Frank Kleibergen. Sample code for installing “reghdfe” package provided under “Example” section. 30 5158.7 outreg John Luke Gallup (Click on package name for deion) 可以看到outreg命令比较火热。小编后期将终点推荐stata中的命令使用方法。 ssc new 有的外部命令无法安装是因为现用版本的stata已经有和此外部命令相同的功能，比如dropvars，13.1版本中能搜索安装后也不可以用，因为基本命令drop即可实现批量删除变量。 Sergio Correia, 2018.
