smooth.fdPar | R Documentation |
Smooth data already converted to a functional data object, fdobj, using directly specified criteria.
smooth.fdPar(fdobj, Lfdobj=NULL, lambda=1e-4,
estimate=TRUE, penmat=NULL)
fdobj |
a functional data object to be smoothed. |
Lfdobj |
either a nonnegative integer or a linear differential operator object. If
|
lambda |
a nonnegative real number specifying the amount of smoothing to be applied to the estimated functional parameter. |
estimate |
a logical value: if |
penmat |
a roughness penalty matrix. Including this can eliminate the need to compute this matrix over and over again in some types of calculations. |
