Fisher adlai conditional tests
WebRelative Risk, Odds, and Fisher’s exact test I) Relative Risk A) Simply, relative risk is the ratio of p 1/p 2. For instance, suppose we wanted to take another look at our Seat belt safety data from Florida: Safety equipment Injury in use Fatal Non-fatal Total None 1,601 165,527 167,128 Seat belt 510 412,368 412,878 p 2 = . p 1 = .00958. WebFisher's exact test is definitely appropriate when the row totals and column totals are both fixed by design. Some have argued that it may also be used when only one set of margins is truly fixed. This idea arises because the marginal totals n 1 +, n + 1 provide …
