How to add row to Stargazer table to indicate use of fixed effects

Question

I just run my regression including fixed effects, in this case id_school. Next I omitted all the dummy variables from my stargazer tab, so I can save some space.

The thing is I want to include a row in my tab in order to report that I used Fixed Effect like :Fixed Effects Yes NO ...Something like the image.

Thank you. enter image description here

Use the add.lines argument to stargazer() to add a row to your table that indicates you used fixed effects. – Sustentacular

Note that I edited your question to be about stargazer and not rstudio. You also asked a second question about your data being balanced, which I deleted from here, since it is unrelated. If you still have that question, ask it in a new stackoverflow post. – Sustentacular

Answer 1

Simple option is to use Stargazer add.lines, e.g.

#load a panel data
data("Wages", package = "plm")

#plain vanilla OLS
model1 <- lm(lwage ~ exp + union + ed + black, data=Wages)
# Least-Squares Dummy Variables model
model2 <- lm(lwage ~ factor(ind) + exp + union + ed + black, data=Wages)

library(stargazer)

stargazer(model1, model2, omit = '[i][n][d]', type='text',
add.lines=list(c('Fixed effects', 'Yes','No'))
)

Returns:

If you are using Latex, another option is to use starpolishr available from github. This allows you to set the position of the line to be added.

library(stargazer)
library(tidyverse)
library(starpolishr)
stargazer(model1, model2, omit = '[i][n][d]', type='latex') %>%  
star_insert_row(insert.after=14, 'Fixed effets & Yes & No \\\\ ') %>% cat(file='foo.tex',sep='\n')

Output:

Puisne

Note that my model probably does not make any sense, so please disregard the coefficient estimates :) – Grilse

Hey Otto, how do you do if you have two fixed effects? One for individual and one for time? – Breault

You can easily add two lines by e.g. add.lines=list(c('Individual fixed effects', 'Yes','No'), c('Time fixed effects', 'No','Yes')) – Grilse

Or alternatively just chain two star_insert_row() commands – Grilse

Sorry. My question was more on how to ignore individual and time fixed effects in the table. Somehow I'm able to ignore the time fixed effects but not individual fixed effects at the same time. If you have clue about this, I would appreciate it. – Breault

Sorry, I do not understand what you are trying to do. Maybe you should try to ask a separate question? – Grilse
