deriv_link function

Function to compute the derivatives of the link function needed by the algorithm

deriv_link(link = c("logit", "probit", "cloglog", "loglog", "cauchit"))

Arguments

• link: One of "logit" (default), "probit", "cloglog", "loglog" or "cauchit".

Returns

A list with the link function and the 1st, 2nd and 3rd derivatives with respect to the argument
