Knots Method for GeDS, GeDSgam, GeDSboost
Description
Method for the generic function knots
that allows the
user to extract the vector of knots of a GeDS, GAM-GeDS or FGB-GeDS fit of a
specified order contained in a "GeDS"
, "GeDSgam"
or
"GeDSboost"
class, respectively.
Usage
## S3 method for class 'GeDS'
knots(Fn, n = 3L, options = c("all", "internal"), ...)
## S3 method for class 'GeDSgam'
knots(Fn, n = 3L, options = c("all", "internal"), ...)
## S3 method for class 'GeDSboost'
knots(Fn, n = 3L, options = c("all", "internal"), ...)
Arguments
Fn |
The |
n |
Integer value (2, 3 or 4) specifying the order ( |
options |
A character string specifying whether " |
... |
Potentially further arguments (required for compatibility with the definition of the generic function). Currently ignored, but with a warning. |
Details
This is a method for the function knots
in the
stats package.
As "GeDS"
class, NGeDSgam
and
NGeDSboost
objects contain three different fits (linear,
quadratic and cubic), it is possible to specify the order of the GeDS fit
whose knots are required via the input argument n
.
Value
A vector in which each element represents a knot of the GeDS/GAM-GeDS/FGB-GeDS fit of the required order.
