WebMar 31, 2024 · If you have two binary variables, the sign of any relationship just depends on conventions about which state is coded 0 and which 1. There is a grey area between a convention being natural and it being familiar. If anything is even a smidgen towards being causal, it seems usual to code both binaries to yield positive association. WebThe first coefficient looks at the number of matches (1-1 or 0-0) and divides by the total number of variables. If two sites have identical species lists, then this coefficient is equal to one because of c = b = 0. The more species that are found at one and only one of the two sites, the smaller the value for this coefficient. reset this pc from biosWebApr 26, 2024 · 1.
