Go to Post I will never forget Dean's opening lines: "I want you to know that I am here under protest. I believe that everything you are doing here is repugnant and ethically wrong. And now I am going to tell you why..." And for the next 35 minutes, that is exactly what he did. - dlavery [more]

Just heard back from the author. He wrote that paper as a class assignment as an undergrad. It was never published.

He agrees Eq12 is wrong. So equations 13 thru 17 are also wrong, as is the simulation.

Baumback used those equations as the basis for her simulation, so it's wrong too.

Internet advice: caveat utilitor
