Evaluation of thin plate spline surface.
Usage
predict.tps(out, x, lambda, derivative=0, model=NA)
Arguments
out
|
Fitted tps object.
|
x
|
Matrix of x values on which to evaluate the thin plate spline surface.
If omitted, out$x will be used.
|
lambda
|
Smoothing parameter. If omitted, out$lambda will be used.
|
derivative
|
Derivative of function is returned if derivative=1.
Generic argument that may be used to pass a different lambda.
|
Value
Vector of predicted responses. If derivative=1 a vector of
derivatives or a matrix of partial derivatives is returned.See Also
