This is a matrix object used in the construction of family.rsm
objects. It is of mode list, and has dimension c(3,5).
The 5 columns in
rsm.distributions[[functionName, familyName]]
represent the distributions student (Student's t),
logistic, logWeibull, extreme (Gumbel
or extreme value) and Huber (Huber's least favourable).
The rows g0, g1 and g2 contain functions that
define minus the corresponding log density and its first and second
derivatives. They take a single argument for the families
logistic, logWeibull and extreme, while for the
families student and Huber they have a further
argument, respectively df and k, which denote the
degrees of freedom and the tuning constant.
This object is used by the functions make.family.rsm and,
indirectly, by rsm when constructing a family.rsm
object. See the documentation of family.rsm.object
and make.family.rsm for additional details.
