maxlogL
object)NegInv_link
object provides a way to implement negative inverse link function that
maxlogL
needs to perform estimation. See documentation for
maxlogL
for further information on parameter estimation and implementation
of link objects.
NegInv_link()
NegInv_link
is part of a family of generic functions with no input arguments that
defines and returns a list with details of the link function:
name
: a character string with the name of the link function.
g
: implementation of the link function as a generic function in R
.
g_inv
: implementation of the inverse link function as a generic function
in R
.
There is a way to add new mapping functions. The user must specify the details aforesaid.
A list with negative inverse link function, its inverse and its name.
maxlogL
Other link functions:
log_link()
,
logit_link()
