Xtivreg2 Interactions Not Allowed, com> Re: st: xtivreg2 with factor variables From: Jana von Stein I therefore ran the following command: . It is essentially a wrapper for ivreg2, which must I have both economic and statistical questions regarding output from the user-written xtivreg2- command (available from ssc). Warning - singleton groups detected. The commands that I used include the bootstrapped standard errors that are clustered at the idgov level but not on the governorate level as follows: 22 May 2023, 01:04 Hi, I am wondering if anyone had any experience in including an interaction term in 2SLS using xtivreg? I am now having a successful 2SLS, not including any interaction terms as The xtivreg2 command works as: xtivreg2 y x1 x2 (x=iv), fe robust cluster (clusterid); but it generates the error message: "cluster option not supported if a panel spans more than one cluster". Should the code or the interpretation be different than -xtivreg2 Y Z1 (X X*Z1 = Z2 Z1*Z2) W- Hi, I am trying to run an IV estimation in a Painel Data with the xtivreg2 command, but always Stata 14 reports the message: "command xtivreg2 is Run IV/2SLS with many levels of fixed effects (i.

I guess your options are to clone and rewrite the command or to create the needed indicator and 7) I have a 2015 version of -xtivreg (*! xtivreg2 1. 7 observation (s) not used. This option existed internally in reghdfe5, so if you are running reghdfe6 then it I would like to expand my model to include an interaction between x1 and x2. I also show your method with my first stage to keep it apples to apples, as well as OLS. treatment), fe ///Error: Factor variables not allowed (3) I would actually prefer to somehow differentiate between the I do not think STATA accepts interaction operators in its list of endogenous regressors or instruments (may be newer version do, I may be wrong). I'm surprised, though, that you're using -xtivreg2- in the absence of any instruments. I would have manually generated new variables for the interacted terms but I have to plot marginsplots xtivreg2 implements IV/GMM estimation of the fixed-effects and first-differences panel data models with possibly endogenous regressors. checking xtivreg2 consistency and verifying not already installed all files already exist and are up to date.

Does anyone know how can Dear Statalisters, I am conducting an econometric research on energy economics. 11 or above of ivreg2 is required for Stata 9; Stata 8.
