I would like to ask if the standard error in the CBC logit output is actually standard deviation and if we need to divide it by square root of the sample size, in order to obtain the standard error?
The background to this question is we want to find out the marginal willingness-to-pay (WTP), using this equation:
mWTP = Difference in utility between two levels/gradient of the graph utility against cost
To find the 95% confidence interval of mWTP, we need the standard error of the difference in utility between two levels.
Thanks for your help!
