WebJun 21, 2024 · $\begingroup$ Thanks so much, just to confirm I am understanding this correctly. Let's say the outcome was a continuous variable, then the estimated coefficient (0.04479) is still the difference in the outcome variable for x = 1 compared to the group of x=0, it's just that the outcome group has a larger range (like if it went from 0-100 instead … WebMay 26, 2024 · I started by estimating the regressions with glm and correcting the standard errors with coeftest from the lmtest package and vcovPL from the sandwichpackage. Subsequently, I used svydesign and svyglm from the survey package to estimate a weighted model and corrected the standard errors again the same way.

WebMar 1, 2024 · Extracting coeftest results into a data frame. I'm trying to extract model coefficients from R into a data frame that I can then combine into one large dataset with some other model results from Stata. model_1_coef <- lmtest::coeftest (model1, vcov = sandwich::vcovHC) This seems to just create an object of class 'coeftest', and coercing … WebNov 25, 2024 · Simple answer: no there is not. And also there is no reason for doing this. The coeftest () function is using the values of your given model. With stats4::coef the coeftest function is taking the coefficients of the model. It would be possible to extract the r^2 value if the function intends to do it. Also the imtest coeftest () only returns a ...

WebLooking to the function itself I realized that NeweyWest actually calls vcovHAC. Empirically the results of coeftest (mymodel, vcov. = vcovHAC) and coeftest (mymodel, vcov. = NeweyWest) are mad different. While vcovHAC is somewhat close to the naive lm results, using NeweyWest all coefficients turn insignificant (tests even close to 1).
