WebIn R this is done via a glm with family=binomial, with the link function either taken as the default (link="logit") or the user-specified 'complementary log-log' (link="cloglog"). Crawley suggests the choice of the link function should be determined by trying them both and taking the fit of lowest model deviance. WebFitting this model looks very similar to fitting a simple linear regression. Instead of lm() we use glm().The only other difference is the use of family = "binomial" which indicates that we have a two-class categorical response. Using glm() with family = "gaussian" would perform the usual linear regression.. First, we can obtain the fitted coefficients the same way we …
