Prediction intervals for beta regression
...get an estimate of uncertainty surrounding a single predicted value from a beta regression model (this is similar to a logistic glm - in that it involves a link function and linear predictor - but it uses the beta distribution rather than discrete binomial). For example:
library(betareg)
data("GasolineYield")
test.model<-betareg(yield~gravity+temp,data=GasolineYield)
...and I would like a measure of uncertainty for a single predicted value, such as:
predicted.value<-predict(test.model,newdata=GasolineYield[20,],type="response")
Ideally, this interval estimate would be a confidence...
