I am trying to create a table of a multivariable logistic regression model using stargazer. I would like to include odds ratios and their confidence int
You can use the ci.custom argument to feed stargazer a list with custom confidence intervals (first column is the lower bound, second column is the upper bound). In your example, all you have to do is call:
stargazer(mylogit, coef = list(OR.vector), ci = T,
ci.custom = list(CI.vector), single.row = T, type = "text")
Alternatively, you can define your own function to exponentiate values and simply apply this function to your coefficients and/or confidence intervals (using arguments apply.coef and apply.ci):
exponentiate <- function(x) exp(x)
stargazer(mylogit, ci=T, apply.coef=exponentiate, apply.ci=exponentiate,
single.row = T, type="text")
