I am a stata user and I was wondering if you could help me with the following two questions. STATA中，xtreg,re命令与xtgls命令有什么区别？前者不就是采用FGLS回归方法吗？不是和后者一样吗？但实际得出的系数值有少许的差异。这是在没有控制自相关与组间异方差的情况下的XTGLS回归，如果控制了，则系数值差异会比较大。向 In both case, the estimator used should be the GLS, but I do not understand what is the difference between using the two different commands (xtgls, p(h) or xtreg, re robust). 0017811/0. xtpcse— Linear regression with panel-corrected standard errors 5 示例1 文献来源. 固定效应模型估计： xtreg xtreg lngdp lnfdi lnie lnex lnim lnci lngp,fe.

Given that -xtreg, re- is referred to on the help file as "GLS random-effects (RE) model", I am puzzled that -xtgls- with default options (and -xtpcse-) produces the same coefficients as -regress- and different from both -xtreg, re- and -xtreg, mle-.

I found a Fellow Statalisters Thanks to Kit Baum, there is now a new package -xcontract- downloadable from SSC. What, in essence, is the "best" model to run for this analysis? I understand the difference between fe So I started searching for the differences between xtreg and xtpcse by running regressions when I realised that xtpcse with country dummies is the same as xtreg, fe and xtpcse with no dummies is the same as xtreg, re. xtset id year. PS: Crossed in cyberspace with Jesse's helpful reply, that, interestingly, shows different takes. General Least Square (GLS) xtgls kemandirian kota PDRB i. Robust reg kemandirian kota PDRB,ro 2. There are additional panel analysis commands in the SSC mentioned here Normally, when I run regressions for panel data in Stata using these three commands (xtreg,areg, reghdfe), the results regarding the coefficients of variables are quite similar; the only differences are about the R-square and In order to follow your advice and considering that now, with xtreg, I intend to do further robust testing which is either using xtpcse/xtgls/xtscc also as Hoechle 2014 suggestion Kindly advice. 5495334 e | . 54 #> corr(u_i, Xb) = -0. 05 mô hình FEM là phù hợp hơn so với mô hình OLS Chạy hồi quy REM 怎么stata中实现xtgls+ols,请教各位： 我使用面板数据进行回归时，通过相关检验发现有异方差及截面相关，因此使用的xtgls命令。但是一外审意见坚持要我使用xtgls+ols，并认为这是等同于xtreg+fe的估计方法，但是我不知道怎么在stata中实现这个啊？谢谢各位啊。 2．同时处理组内自相关、异方差和组间同期相关的可行广义最小二乘估计.

Daniel Schaefer. webuse grunfeld, clear. When should we use xtgls over xtreg? 2) How come the xtgls command does not produce an R-squared? And, how can I obtain an R-squared when using the xtgls command. 如果在不考虑稳健标准误的情况下，这四条命令得到的结果是一致的，很不幸我们现在都要考虑稳健标准误。 关于选择xtgls，xtreg fe还是xtscc between panel iand panel jwhen the panels’ periods are matched, and I is a T i by T xtgls produces full FGLS parameter and variance–covariance estimates. for your panel I would recommend -xtgls-, not -xtreg-. xtgls with igls + corr(ar1) option would mean maximum likelihood estimation, WLS with exponential correlation. Running xtreg fe brings up some nice results akin to much of the literature (all significant bar violence; aid/gdp being negative and initial gdp per capita being I understand that -xtgls- is the preferred model over -xtreg- given that T>N, as you mentioned.

More details (and an excerpt of your data via -dataex-) are highly recommended to increase your chances of getting helpful replies. 0646093=1 to three decimal places. 2) and Wooldridge (2009, chap. The RE is just a weighted average of the within and between estimators. OTR 4 This video guides about Generalized Least Squares Approach in Stata 17 [Remedy for Random Effects Model]Commands:xtgls y x, panels(heterosk) corr(psar1) nolo 加入 个体固定效应 和时间固定效应，对比reg， xtreg ，areg，reghdfe的效果，都采用稳健标准误。 暂未采用 聚类标准误 （正常写paper应该加聚类标准误，不过加了容易系数不显著）。. 24 Mar 2019, 12:04. xtreg can estimate fixed-effects (within), between effects and random effects (mixed) models as well as population averaged models. and the community-contributed command -reghdfe- (as you're kindly requested to define it, for reasons that are well explained in the FAQ), in my opinion most depends on whther you want to numerically retrieve more than one fixed effect or not; in the latter case I would go -xtreg,fe-. xtreg kemandirian kota PDRB,fe 2. Xtregar uses a different estimating procedure than the feasible gls? Is this because of different initial assumptions? Most of the literature seems to indicate that omega is unknown and therefore FGLS is used for GLS. xtpcse—Linearregressionwithpanel-correctedstandarderrors Description Quickstart Menu Syntax Options Remarksandexamples Storedresults Methodsandformulas Acknowledgments References Alsosee Description xtreg with its various options performs regression analysis on panel datasets. 3405 Prob > F = 0 Postestimation tools for xtgls : xthdidregress: Heterogeneous difference in differences for panel data : xtheckman: Random-effects regression with sample selection: Postestimation tools for xtreg StataNow : xtregar: Fixed- and random-effects linear models with an AR(1) disturbance: xtregar postestimation: Postestimation tools for xtregar : 关于选择xtgls，xtreg fe还是xtscc，求助大神！！ - Stata专版 - 经管之家 (原人大经济论坛) Dhulika: you applied so many different models for T>N panel datasets that I find hard to advice about the best approach. xttest3 2) my mistake: -xtgls- does not include time effect by default, too: so I'd add it. xtgls vs. 0000< 0. What is the difference between xtreg re and xtgls? How do we know which one to use? A related problem we have is to get R^2-values outputted with outreg2 for our panel data Similar approach is applied in frontier models, but there the distribution of u (i) is half-normal or gamma. melogit, mepoisson) or using the xt toolkit, including xtset and xtreg. , et al. 5 组间异方差的检验 (xttest3) * Greene 提供了对组间异方差的wald 检验 * 原假设 不同个体的扰动项方差均相等 * 此 wald 检验可通过 xttest3 实现 * 该命令只能在运行命令 xtreg, fe 或 xtgls 之后才能使用 * ssc install xttest3 qui xtreg lnc lnp lnpmin lny i.

Train(2002) has made some codes in Gauss available on his web site for the Mixed logit for panel data. year, fe. In this FAQ we will try to explain the differences between xtreg, re and xtreg, fe with an example that is taken from Carlo Lazzaro, Thank you for your reply. xtreg, fe estimates the parameters of fixed-effects models: . If you have many panels relative to periods, see[XT] xtreg and[XT] xtgee. So I started searching for the differences between xtreg and xtpcse by running regressions when I realised that xtpcse with country dummies is the same as xtreg, Can unit/time dummies be included with PCSE or XTGLS? 0. * .
