Fisher ratio python
WebNote also that fisher.test() in R for \(2 \times 2\) tables will give so-called "conditional estimate" of the odds-ratio so the value will be different (in this case, approximately 6.408). Notice the difference between the exact and asymptotic CIs for the odds ratio for the two-sided alternative (e.g., \(\theta\ne1\)). The exact version is larger. WebCompute the relative risk (also known as the risk ratio). This function computes the relative risk associated with a 2x2 contingency table ( [1], section 2.2.3; [2], section 3.1.2). Instead of accepting a table as an argument, the individual numbers that are used to compute the relative risk are given as separate parameters.
