Prior distribution in Bayesian efficient design

Dear professor

I'm now making a Bayesian efficient design and want to ask some questions about defination of prior distribution. Like my code, I have set these variables to follow normal and uniform distributions. How should I implement them as log-normal distributions?

Comparison analysis of Bayesian D-error and fixed D-error

Dear Dr Bilemer,
I'm using Ngene to generate the SP survey design first time, and I created a Bayesian efficent model to complete the design. In the end, I found the Bayesian mean D-error was larger than fixed D-error. The results are as follows.

Fixed Bayesian mean
D error 0.186766 0.355442
