# ReLogit model from zelig package in R: how to get the estimated coefficients? [closed]

I tried to get the estimated coefficients from the relogit model of the Zelig package, but R returns NULL in the console when I run the script. Let's see the following example taken from http://ftp.uni-bayreuth.de/math/statlib/R/CRAN/doc/vignettes/Zelig/relogit.pdf :

library(Zelig)

data(mid)

z.out1 <- zelig(conflict ~ major + contig + power + maxdem + mindem + years,
data = mid, model = "relogit", tau = 1042/303772)
summary(z.out1)

z.out1$coefficients  I got the following output:  Call: relogit(formula = form, bias.correct = bias.correct, case.control = case.control, tau = tau, data = data) Coefficients: Estimate Std. Error z value Pr(>|z|) (Intercept) -7.508e+00 1.793e-01 -4.188e+01 1.535e-304 major 2.432e+00 1.572e-01 1.547e+01 4.556e-52 contig 4.108e+00 1.573e-01 2.612e+01 3.852e-136 power 1.054e+00 2.168e-01 4.861e+00 1.228e-06 maxdem 4.804e-02 1.004e-02 4.783e+00 1.805e-06 mindem -6.413e-02 1.277e-02 -5.020e+00 5.444e-07 years -6.293e-02 5.692e-03 -1.106e+01 6.687e-28 Degrees of Freedom: 3125 Total (i.e. Null); 3119 Residual Null Deviance: 3979 Residual Deviance: 1869 AIC: 1883 Prior correction performed with tau = 0.003430204 Rare events bias correction performed > z.out1$coefficients
NULL


Then I tried to run the following script from the same model, following http://docs.zeligproject.org/en/latest/zelig-relogit.html :

z.out1$getcoef  but I got the same NULL answer from the console. How I can get the coefficient values vector? ## 1 Answer It should be z.out1$getcoef(), getcoef() is a function call. It will return a list, the coefficient vector is thus z.out1\$getcoef()[[1]].

The normal way, i.e. coef(summary(MODEL)) as we will do for glm etc, doesn't work for Zelig.
