Hi Nick my dependent variable is a proportion (of the budget that
given a budget constraint individuals are willing to give up)
so I used  logit link function to ensure linearity and binomial family
distribution.. For example for 19 in 100 risk reduction I get a
coefficent of -.657211*** and If i use predict the mean WTP is 0.20
which makes sense .. but the SD is 0 .. I want to get CI for the mean
.. maybe boostrapping is an option? I know how to do for DCE where you
have a ratio of the coefficent (delta or boostrapping or parametric
boostrapping) but I have no clue how to make CI for eman WTP estimate
from regression ..
