Display p-values under 0.1 in r stargazer

Question

I have regression coefficients at p-value 0.06. The output table of stargazer does not display the dot (.) signalling p-values under 0.1. How do I make stargazer to signal p-values below 0.1 in the output table?

*It would be hard to find or create a reproducible example with p-values above 0.05 and below 0.1. If needed, I'll try and find something. But hopefully this is a softball question with a quick solution.

You can do it with the argument star.cutoffs = c(.1, .05, .01) or whichever levels you prefer. If you need to set the symbols, you can use the argument star.char = c(".", "*", "**") to specify the symbol corresponding to each significance level. – Merits

This worked, thanks. Can you post it as an answer? – Entrain

Please note, when using this solution - which works - you need to adjust the note that appears at the bottom of the table, using the notes = c("+ p<0.1; * p<0.05; ** p<0.01; *** p<0.001") attribute and setting notes.append=FALSE" – Goddamn

Answer 1

You can do this with the star.cutoffs and star.char arguments. Some fake data below to demonstrate:

library(stargazer)

# Generate some fake data
set.seed(10)
x <- rnorm(10)
x1 <- rnorm(10)
e <- rnorm(10)
y <- 10 + x + 2*x1 + e

# Estimate a model
m1 <- lm(y~x + x1)

# We can see that we have three different levels of sig at typical cutoffs
summary(m1)

#> Call:
#> lm(formula = y ~ x + x1)
#> 
#> Residuals:

# We will make the 10% level a plus sign, and stars for .05, .01 and .001
stargazer(m1, type = "text",
          star.char = c("+", "*", "**", "***"),
          star.cutoffs = c(.1, .05, .01, .001))
