Fisher exact p value
WebFisher’s Exact Test is a statistical test used to determine if the proportions of categories in two group variables significantly differ from each other. To use this test, you should have … Web$\begingroup$ Update: I'm still looking for a test that actually calculates the one-sided boundary, rather than halving the two-sided p value. Comparing fisher.test p values from the example above, two-sided is 0.272 but one-sided greater-than is 0.209. This means it's not symmetrical (.209 in upper tail and .063 in lower tail).
