Overview

About

Maintained by Stefan KloppenborgCRAN page ↗GitHub ↗Website ↗Issues ↗

A companion package to 'cmstatr' https://cran.r-project.org/package=cmstatr. 'cmstatr' contains statistical methods that are published in the Composite Materials Handbook, Volume 1 (2012, ISBN: 978-0-7680-7811-4), while 'cmstatrExt' contains statistical methods that are not included in that handbook.

Changes in 0.5.0

Added function for computing "one-sample" equivalency factors. This function should produce the same values as cmstatr::k_equiv(), but is written in C++ and is hence faster.
Renamed the function p_equiv() to p_equiv_one_sample(). The function p_equiv() will still work but will produce a warning and may be removed in a future version of this package.
Reduced the tolerance for root finding from DBL_EPSILON^0.25 (about 1.2e-4) DBL_EPSILON^0.5 (about 1.5e-8). This may affect the results of k_equiv_two_sample, p_equiv_two_sample and p_equiv_one_sample and should produce more accurate results for each of these functions. You can expect to see the largest differences with very low p-values and alpha values.
In the function power_sim_dual(), changed the internal data types used to count the number of acceptance/equivalency failures from int to unsigned long long to prevent overflow when replicates is greater than 46340.

This package now checks for conflicting function names and will produce a message when attached, similar to the way that the tidyverse package produces a conflict message when attached.
In the accompanying website [https://cmstatrExt.cmstatr.net], added a new calculator for equivalency thresholds.

Install

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

install.packages("cmstatrExt", 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("cmstatr/cmstatrExt")

Development version from cmstatr/cmstatrExt. 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-cmstatrext

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-cmstatrExt

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-cmstatrExt

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.
