Dear R help, I use the package plm the function plm() to analyse a panel data and estimate a fixeffect model. I use the code as follow : fe <- plm(y~x+z, data, model = "within") I want to use bootstrap to estimate standard error I consult the paper plm.pdf , but I can't find any answer. Can I estimate variance with bootstrap?
