Lwls1D: One dimensional local linear kernel smoother

In fdapace: Functional Data Analysis and Empirical Dynamics

One dimensional local linear kernel smoother

Description

One dimensional local linear kernel smoother for longitudinal data.

Usage

Lwls1D(
  bw,
  kernel_type,
  win = rep(1L, length(xin)),
  xin,
  yin,
  xout,
  npoly = 1L,
  nder = 0L
)

Arguments

bw	Scalar holding the bandwidth
kernel_type	Character holding the kernel type (see ?FPCA for supported kernels)
win	Vector of length N with weights
xin	Vector of length N with measurement points
yin	Vector of length N with measurement values
xout	Vector of length M with output measurement points
npoly	Scalar (integer) degree of polynomial fitted (default 1)
nder	Scalar (integer) degree of derivative fitted (default 0)

Value

Vector of length M with measurement values at the the point specified by 'xout'
