Why does my fe with demeaned data ( lm() ) not reproduce coefficients from plm(), lfe() and lsdv?

I am trying to reproduce fixed effects coefficients for panel data using different packages and techniques: (1) plm(), (2) lfe(), (3) dummy-lsdv with lm(), and (4) demeaned-fe with lm(). My data set consists of 1581 observations and 13 variables. It…

feols - fixest: loop over dependent variable

I am trying to loop over a set of dependent variables using the feols function from the fixest package. In base using lm or in lfe::felm I would simply use the get() function. With fixest, I receive an error. Why is that, and is there a way to get…

Marginal effects / interaction plots for lfe felm regression object

I need to create an interaction / marginal effects plot for a fixed effects model including clustered standard errors generated using the lfe "felm" command. I have already created a function that achieves this. However, before I start using it, I…

How to export the regression table for the results with robust standard error or clustered standard error with package lfe?

Using the package lfe, I can generate the regression results with either robust standard error or clustered standard error using command felm. For the standard regression, I can export the regression table with the texreg package using function…

Fixed Effects Regression Constant / Intercept Using FELM in R

How does one obtain the intercept ('constant') when using the felm function (of the lfe package) for panel data with fixed effects? Reproducible example: library(lfe) set.seed(42) x <- rnorm(100000) f1 <- sample(10000, length(x), replace=TRUE) f2 <-…

Coercing felm R-object into lm form or some other way of getting it printed in a LaTeX table

I am using the lfe package in R to do some regression with lots of fixed effects, so direct lm is out of the question (and since the fixed effects are not individual-level, so is plm). I get the output with no problems but now I'd like to use it in…

Interaction terms using colon does not work for error clustering in felm

I would like to cluster errors in my fixed effect regression at the origin-by-year level. When I use : (i.e., year:origin) as clusters in the felm formula, it seems like felm actually clusters error in a two-way manner (i.e., year + origin). When I…

I have run this regression without any problems and I get 4 coefficients, for each interaction between econ_sit and educ_cat. Econ_sit is a continous variable, and educ_cat is a categorical variable from 1-6. How can i plot the coefficients only for…

Using broom::tidy on felm result with clustered standard errors

I'm trying to extract point estimates and confidence intervals from a panel data model. The following reproduces the error using the canned example from the lfe documentation. The only small change I've made is to cluster standard errors at the…

Arity of + and - operators in Lisp Flavored Erlang

As I am just starting with LFE I've been trying out some examples from the book (SICP, LFE version) while reading the chapters. In exercise 1.4 page 76 I see the expressions #'+/2 and #'-/2. So I enter into the REPL (funcall #'+/2 1 2) and get (as…
