This function is used with the family functions in
glm().
Given the name of a link, it returns a link function, an inverse link
function, the derivative \(d\mu / d\eta\) and a function
for domain checking.
Usage
make.link(link)
Arguments
link
character; one of "logit",
"probit", "cauchit", "cloglog", "identity",
"log", "sqrt", "1/mu^2", "inverse".
Value
A object of class "link-glm", a list with components
linkfun
Link function function(mu)
linkinv
Inverse link function function(eta)
mu.eta
Derivative function(eta) \(d\mu / d\eta\)
valideta
function(eta){ TRUE if
eta is in the domain of linkinv }.
