==Motivation for having own article==
Line 12 ⟶ 18:
But that can be read directly off of the chart given in the article, in one calculation, by the definition of conditional probability:
:<math> P( Cancer = True | Test = True) = \frac{ P(Cancer = True \
That seems '''way''' easier than the complicated multi-step process described in the example. So why would you ever do it that way?

==Footnotes added==
I added more footnotes from a reference, as requested by the tag [http://en.wikipedia.org/w/index.php?title=Pre-_and_post-test_probability&action=historysubmit&diff=446947036&oldid=446946032]. The article surely needs more referenced entries, but I don't think it lacks specifically in in-line citations of existing references.

== Disadvantage of Likelihood ratios ==
I deleted the disadvantage of LR in the table because it is possible to do a calculation of likelihood ratios for tests with continuous values or more than two outcomes which is similar to the calculation for dichotomous outcomes; a separate likelihood ratio is simply calculated for every level of test result and is called interval or stratum specific likelihood ratios.<span style="font-size:x-small;">{{cite journal | doi = 10.1067/mem.2003.274 | author = Brown MD, Reeves MJ. | year = 2003 | title = Evidence-based emergency medicine/skills for evidence-based emergency care.

:I didn't know that was possible. Thanks for pointing this out {{=)}} I mentioned it in the article too. [[User:Mikael Häggström|Mikael Häggström]] ([[User talk:Mikael Häggström|talk]]) 08:16, 18 February 2015 (UTC)
== Subjectivity discussion is confusing and irrelevant ==
The use of the term "subjective" ignores that pre-test probability is derived from studies that are actually pretty straight forward. For example, HIV testing, you have some defined indication for testing and you simply count how many positive results you get, and how many negative. What is subjective about that? The editor using "subjective" misinterprets the subject matter of pretest probability away from the formal term to what "pre-test probability" would mean in colloquial language - what is the probability that my patient has HIV? Or is that all in my mind? [[Special:Contributions/205.203.58.1|205.203.58.1]] ([[User talk:205.203.58.1|talk]]) 20:18, 28 October 2016 (UTC)
:I moved the subjectivity section to the bottom, because, as you say, it is not that relevant. The same can be argued for any kind of [[probability]], but that's rather a discussion about [[Determinism]].
