Hi,

 

Is there a simple command for computing the standard error of a
combination of parameter estimates in a GLM?

 

For example:

 

riskdata$age1 <- riskdata$age

riskdata$age2 <- ifelse(riskdata$age<67,0,riskdata$age-67)

 

model <- glm(death~age1+age2+ldl,
data=riskdata,family=binomial(link=logit))

 

And we want to find the standard error of the partial linear predictor
for the combination of the two age parameters, age1+age2, at some age X,
without needing to separately use the covariance matrix?

 

Thanks,

 

Mark Donoghoe
