gee
I am trying to use gee() to calculate the robust standard errors for a logit model. My dataset (zol) has 195019 observations; winner, racebl, raceas, racehi are all binary variables. ID is saved as a vector of length 195019 with alternating 0's and 1's. I get the following error message. I also tried the same command with corstr set to "independence" and got the same error message. > ID <- as.vector(array(0, n...

Robust standard errors
I am trying to calculate robust standard errors for a logit model. I installed the package "car" and tried using hccm.default, but that required an lm object. Is there some way to do a similar operation for a glm object? x <- hccm.default(glm(winner ~ racebl + racehi + raceas + inchi + incmed + edhs + edcol + edba + agec1 + agec4 + sex + margin + regla + regbay + regsc + libcon+ pdem + poth, data = zol, family = binomial, weights = NULL)) Error in hccm.default(glm(winner ~ racebl + racehi + raceas + inchi + : requires an lm object > Thanks, Nirmala Ravishan...
