Talk:2059: Modified Bayes' Theorem
Right now the layout is awful:
- "If the..."
- should look like this:
- "If P(C)=1 the..."
But there is more wrong right now. Look at a typical Wikipedia article, the Math-extension should be used for formulas but not in the floating text. --Dgbrt (talk) 20:03, 15 October 2018 (UTC)
- Credit for a good explanation though. It made perfect sense to me, even though I didn't understand it. 220.127.116.11 04:14, 16 October 2018 (UTC)
I removed this, because it makes no sense:
- As an equation, the rewritten form makes no sense. is strangely self-referential and reduces to the piecewise equation . However, the Modified Bayes Theorem includes an extra variable not listed in the conditioning, so a person with an AI background might understand that Randal was trying to write an expression for updating with knowledge of i.e. , the belief in the hypothesis given the observation and the confidence that you were applying Bayes' theorem correctly , for which the expression makes some intuitive sense.
Between removing it and posting here, I think that I've figured out what it's saying. But it comes down to criticizing a mistake made in an earlier edit by the same editor, so I'll just fix that mistake instead.

What about examples of correct and incorrect use of Bayes' Theorem? I don't feel equal to executing that, but DNA evidence in a criminal case could be illuminating. As a sketch, it may show that of 7 billion people alive today, the blood at the scene came from any one of just 10,000 people of which the accused is one. Interesting, but not absolute. At least 9,999 of the 10,000 are innocent. Probability of mistake or malfeasance by the testing laboratory also needs to be considered. Then there's sports drug testing, disease screening with imperfect tests and rare true positives, etc. [email protected] 18.104.22.168 09:42, 17 October 2018 (UTC)
