Overview

About

Maintained by David WinsemiusCRAN page ↗GitHub ↗Issues ↗

Produces a smooth estimate of the hazard function for censored data.

Changes in 1.2.6.5

Bug fixes

Fixed a crash in muhaz() when a group has zero events. The default pilot bandwidth calculation (bw.pilot <- endz/8/(nz^.2)) divided by zero when sum(delta) == 0, producing Inf and crashing the downstream Fortran routine. nz is now clamped to a minimum of 1, which yields a finite bandwidth and a correctly flat zero hazard estimate when no events are present. Reported and fixed by Ken Beath <ken@kjbeath.id.au>.

Documentation

Fixed man/muhaz.object.Rd: replaced \arguments with \value / \describe, resolving an R CMD check NOTE ("Rd files without \usage... \arguments should not be documented without \usage").

Package maintenance

muhaz is now maintained by David Winsemius <dwinsemius@comcast.net>, following its orphaning by the previous maintainer.
Added GitHub Actions / R-hub v2 CI configuration for cross-platform checks.

Install

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

install.packages("muhaz", 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("dwinsemius/muhaz")

Development version from dwinsemius/muhaz. 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-muhaz

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-muhaz

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-muhaz

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.
