a specification For the model link Function. This can be a name/expression, a literal character String, a length-one character vector, Or an Object Of Class "link-glm" (such As generated by make.link) provided it Is Not specified via one Of the standard names given Next. The gaussian family accepts the links (As names) identity, log And inverse; the binomial family the links logit, probit, cauchit, (corresponding To logistic, normal And Cauchy CDFs respectively) log And cloglog (complementary log-log); the Gamma family the links inverse, identity And log; the poisson family the links log, identity, And sqrt; And the inverse.gaussian family the links 1/mu^2, inverse, identity And log. The quasi family accepts the links logit, probit, cloglog, identity, inverse, log, 1/mu^2 And sqrt, And the Function power can be used To create a power link Function. [as string]
