I want to estimate the following fixed effect model: y_i,t = alpha_i + beta_1 x1_t + beta_2 x2_i,tx2_i,t = gamma_i + gamma_1 x1_t + gamma_2 Z1_i + gamma_3 Z2_i I can use ivreg from AER to do the iv regression. fm <- ivreg(y_i,t ~ x1_t + x2_i,t | x1_t + Z1_i + Z2_i, data = DataSet) But, I'm not sure how can I add the fixed effects. Thanks! [[alternative HTML version deleted]]

Dear John Fox, Christian Kleiber, and Achim Zeileis, I am attempting to run various independent variable parameters to assess their suitability. Unfortunately, I hit a snag and couldn't get the tests to run properly. When I used ivreg, I got an error message saying: "Error in eval(predvars, data, env) : object 'WageInequality' not found." Can you please help? Model: numeric(WageInequality) = numeric(EffectiveMinimum) + numeric(EffectiveMinimum2) (whereas EffectiveMinimum2 is the quadratic form of EffectiveMin...

Hello, I am looking for some help with this question: how could I test structural breaks in a instrumental variables´s model? For example, I was trying to do something with my model with three time series. tax_ivreg <- ivreg(l_y ~ l_x2 + l_x1+ dl_y | lag(l_x2, -1)+lag(l_x2, -2)+ lag(l_x1, -1)+lag(l_x1, -2)+lag(l_y, -1)+lag(l_y, -2), data=tax1) summary(tax_ivreg) ## after estimating it, something weird happened with the several tests in package "strucchange". For example: cusum <- efp(l_y ~ l_...

...Residual standard error: 1.263 on 4732 degrees of freedom Multiple R-squared: 0.1175, Adjusted R-squared: 0.1163 F-statistic: 105 on 6 and 4732 DF, p-value: < 2.2e-16 Question: Assuming that the above illustration is correct, I was wondering how I could mimic these calculations using the ivreg () in AER or tsls () in sem? Any suggestions? Many thanks in advance, and best wishes, Ranjan -- Important Notice: This mailbox is ignored: e-mails are set to be deleted on receipt.

...c.) in the data frame. Then you don't have to put these things into the model formula. - Employ variable names without spaces, then you don't have to use backquotes. Hopefully, this helps you to resolve the problem. If the problem persists and you believe that this is an error within ivreg, please provide a minimal self-contained and reproducible example.

Hi there, I hope to build a model Y ~ X1 + X2 + X3 + X4 with X1 has two instrumental variable A and B, and X2 has one instrumental variable A. I have searched the R site and mailling list, and known that the tsls() from sem package and ivreg() from AER package can deal with instrumental variable regression, however, I don't know how to formula the model. Any suggestion will be really appreciated. Thanks in advances! Regards, Jinsong

Dear all, I am using the Instrumental Variable approach to estimate the causal effects of TWO endogenous variables in a Mendelian Randomization study. As long as point estimation is concerned, I have no problem: both "ivreg" in library "AER" and "tsls" in library "sem" do the job perfectly. The problems begin when I try to obtain confidence intervals for these two causal effects. Of course, I can take the output from ivreg or tsls and compute the Wald-type confidence intervals usi...

I have upgraded R (from 3.6 to 4.0) and RStudio (from 1.1 to 1.2.5) a few days ago, and Ubuntu from 18.04 to 20.04 yesterday. Since then, R sometimes never terminates when executing certain commands: ivreg (from package AER), summary (of a logit regression) and logitmfx (from package mfx). Sometimes these commands run fine, but most of the time I have to kill the process because R won't terminate the execution, even when pressing the red Stop button in RStudio or doing Ctrl + C when using R in th...

Hi All, I am using R 2.11.0 on a Ubuntu machine. I estimated a model using "tsls" from the package "sem". Is there a way to get Newey West standard errors for the parameter estimates? When estimating the model by OLS, I used "NeweyWest" from the package "sandwich" to get HAC standard errors. But, I am not able to use the same method with the results of the

I would like to know if someone knows about how to replicate this command in R. Is there any library wit...

Hello, I am switching to R from Stata and I am having particular trouble with the transition from Stata's 'xtabond' and 'ivreg' commands to the "plm" package. I am trying to replicate some of the dynamic panel data work using the UK Employment data in Arellano and Bond (1991) and available as 'EmplUK' under the 'plm' package. I have been reading "Panel Data Econometrics in R: The p...

Dear all, I try to conduct a SEM / two stage least squares regression with the following equations: First: X ~ IV1 + IV2 * Y Second: Y ~ a + b X therein, IV1 and IV2 are the two instruments I would like to use. the structure I would like to maintain as the model is derived from economic theory. My problem here is that I have trouble solving the equations to get the reduced form so I can run
