In the documentation for the "family" function which
generates an object of type "family", it is stated that
"...'quasi' can be used to combine any available link and
variance function... The function 'power' can also be used
to generate a powerlink function object for use with 'quasi';
'power' takes an argument 'lambda'. Users can construct their
own families, as long as they have compatible components
having the same names as those, for example, of binomial.
The easiest way is to use 'quasi' with home-made link and
variance objects; otherwise 'make.family' can be used, or
else direct construction of the family object. When passed
as an argument to 'glm' or 'gam' with the default link, the empty
parentheses () can be omitted. There is a print method for
the class 'family'."
As I read it, this indicates that the multinomial family
could be constructed from scratch. Is this true? If so,
has anyone implemented GEE or YAGS with a multinomial family?
Much thanks in advance,
