逻辑回归的误差Zelig R

Question

I'm running a logit model using the zelig package in R.

m3 <- zelig (newdata$bes.Turnout ~  civicduty + newdata$bes.CivicDuty2+newdata$bes.Age, model="logit", data=newdata)

newdata$bes.Turnout is binary, the rest are numerical.

I try to set the values of x.

mcos<- median(newdata$bes.CivicDuty2)
civicmean<-mean(civicduty)  
mage<-mean(newdata$bes.Age)

test<-setx(m3, civicduty=civicmean, newdata$bes.CivicDuty2=mcos, newdata$bes.Age=mage)

I get the following error message:

Error: unexpected '=' in "test<-setx(m3, civicduty=civicmean, newdata$bes.CivicDuty2="      

I have tried the same code for the survival data in Zelig, and here the setx worked.

Any ideas what I am doing wrong and how to fix it?

Answer 1

That call to setx doesn't make sense to me. My best guess is that you want something like

test<-setx(m3, 
           civicduty = mean(newdata$civicduty),
           bes.CivicDuty2 = mean(newdata$bes.CivicDuty2,
           bes.Age = mean(newdata$bes.Age))
