I am trying to use stargazer (Version 5.2) to output the standard summary() results of a regression estimated with Zelig (Version 5.0.13). However, I obtain the error
Error in envRefInferField(x, what, getClass(class(x)), selfEnv) :
‘result’ is not a valid field or method name for reference class “Zelig-ls”
when trying to feed the estimated model into stargazer.
A minimal working example reproducing the error would be
library(Zelig)
library(stargazer)
data("swiss")
z <- zls$new()
z$zelig(Fertility~Education, data=swiss)
stargazer(z)
I assume I need to somehow access the place where the estimated model is stored in the zelig object, but I am having trouble finding it.
As of Zelig 5.0-13 and stargazer 5.2, stargazer doesn't seem to be able to handle Zelig's internal model. As a workaround, you can simply cast it to a "normal" lm to make it work:
stargazer(lm(z$zelig.out$z.out[[1]]), type='text')
Result:
