Here's some numbers for your "expectational analysis"
The probabilities are, as I noted (I really wish you guys would read the posts) are the easy part (relatively). It is assigning the costs that is more difficult and you must do that.
(who talks like that? Seriously?).
Seriously? Scientists, engineers, statisticians, psychologists, researchers, military planners, economists, financial analysts, business men, insurance companies, marketers.... Perhaps a light comes on if I used terms like 'cost function', 'loss function' (
https://en.wikipedia.org/wiki/Loss_function).
Clearly there is too much emotion among you all as sex is involved in the current context. Perhaps an example from another field. During world War II Blechley craked the Enigma machine which allowed the Brits to decode the German Navy's radio transmissions. They received a message that Lincolnshire (? don't remember the actual city) was to be attacked. Clearly they could have moved resources to protect Lincolnshire (if that was indeed the place) but Churchill decided not to. Explicitly or implicitly he did an expectational (or cost function, if you prefer) analysis and decided that the expected loss of that city and its citizenry was less than the expected gains from being able to read the Krauts' mail in the future.
AJ is hiding behind a wall of words.
You are hiding between a wall of stupidity so high that I can't believe that it is for real i.e. I think this is flame bait. Or perhaps people come here only after very heavy consumption of their home brew.
and would be laughed out of any real medical conversation.
Haven't been so far. If your doctor cannot discuss treatment for any condition with you on this basis, he didn't go to medical school. Get another doctor. Now I grant you that when I ask for the probabilities of certain outcomes the answer is often "The sample size isn't big enough." or "That aspect of it hasn't been studied" but in many cases it has and your MD can steer you to research.
I respect your opinions immensely regarding water chemistry, but please stick to what you know.
What I propound in discussing water chemistry is sound science. This is sound science too. Lots and lots of research is expended in studies (not always good studies). Your inability to comprehend it in no way diminishes its validity or worth.
Do you think I make this stuff up in order to look foolish? Have you checked out any of this in a textbook or on the internet? Don't you think it is a little risky to try to challenge something you clearly don't understand (simple though it be)?
