Overview

About

Maintained by Alec StashevskyCRAN page ↗GitHub ↗Website ↗Issues ↗

A set of functions to select the optimal block-length for a dependent bootstrap (block-bootstrap). Includes the Hall, Horowitz, and Jing (1995) doi:10.1093/biomet/82.3.561 subsampling-based cross-validation method, the Politis and White (2004) doi:10.1081/ETC-120028836 Spectral Density Plug-in method, including the Patton, Politis, and White (2009) doi:10.1080/07474930802459016 correction, and the Lahiri, Furukawa, and Lee (2007) doi:10.1016/j.stamet.2006.08.002 nonparametric plug-in method, with a corresponding set of S3 plot methods.

Changes in 0.2.2

Minor Changes

The plot.nppi() function now returns an additional plot for JAB Pseudo Value Stability.

Bug Fixes

In nppi() there was an inconsistency in dimensionality between the jab_point_values and the jab_pseudo_values due to how NA values were handled. This is fixed such that both vectors will always have the same length.

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("blocklength", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("Alec-Stashevsky/blocklength")

Development version from Alec-Stashevsky/blocklength. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-blocklength

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-blocklength

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-blocklength

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
