WebChapter 8. Binomial GLM. A common response variable in ecological data sets is the binary variable: we observe a phenomenon Y Y or its “absence”. For example, species presence/absence is frequently recorded in ecological monitoring studies. We usually wish to determine whether a species’ presence is affected by some environmental variables. WebDetails. family is a generic function with methods for classes "glm" and "lm" (the latter returning gaussian () ). For the binomial and quasibinomial families the response can be specified in one of three ways: As a factor: ‘success’ is interpreted as the factor not having the first level (and hence usually of having the second level).
