Generate a familytoo object.


DESCRIPTION:
       Generates  a  familytoo  object  containing  a   list   of
       functions and expressions used by psglm.

USAGE:
       family(family = gaussian,...)

REQUIRED ARGUMENTS:
family:   a family object

VALUE:
       An object of class "familytoo".

DETAILS:
       This function appends the first four  cumulants  onto  the
       original  family object. psglm needs information about the
       higher order cumulants as well as the  link  and  variance
       functions.   As  yet  only  canonical  link  functions are
       supported.

SEE ALSO:
       cumulants, psglm.

EXAMPLES:
       familytoo()   # Gaussian family with cumulants
       familytoo(binomial)
