Overview

About

Maintained by Bastian SchaeferCRAN page ↗

Nonparametric smoothing techniques for data on a lattice and functional time series. Smoothing is done via kernel regression or local polynomial regression, a bandwidth selection procedure based on an iterative plug-in algorithm is implemented. This package allows for modeling a dependency structure of the error terms of the nonparametric regression model. Methods used in this paper are described in Feng/Schaefer (2021) https://ideas.repec.org/p/pdn/ciepap/144.html, Schaefer/Feng (2021) https://ideas.repec.org/p/pdn/ciepap/143.html.

Changes in 1.1.2

Parallelization for DCS procedure added.
Bandwidth selection of derivative estimation improved.
Additional argument "trim" in surface.dcs for trimming the boundaries of the plot.
Data sets "returns.alv", "returns.bmw", "volumes.alv", "volumes.bmw" added.
Bugs in estimation of derivatives ("KR" and "LP") corrected and corresponding error model are fixed.
Default value in IPI_options$infl_par set to (2,1) for local polynomial regression.

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.1.2) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.
