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. WebFisher's principle is an evolutionary model that explains why the sex ratio of most species that produce offspring through sexual reproduction is approximately 1:1 between males …
