Joint estimation of quantile specific intercept and slope parameters in a linear regression setting.

Changes in 2.1-0

The C computational engine has been rewritten in Rcpp/RcppArmadillo, replacing the legacy .C() interface. qde() and qrjoint() now share a single underlying engine.
Fixed a bug in qrjoint() (not qde()) where observations with zero weight (wt = 0) could produce NaN in the log-posterior, potentially freezing the MCMC chain. Zero-weight observations now correctly contribute nothing to the likelihood, as documented. This has no effect on models fit with the default (all nonzero) weights.
Performance improvements, all exact (no change to the statistical model): Gaussian-process components are now cached and only recomputed for the MCMC blocks that actually change them; a redundant per-grid-point quantile-function evaluation in the base distribution is now computed once per log-posterior evaluation instead of once per grid point; and the per-observation quantile-bracket search now uses binary search instead of a linear scan. Combined, these give roughly a 1.7-1.9x speedup on typical problem sizes with identical statistical results.

Added a more numerically robust Cholesky factorization for the adaptive proposal covariance, with jitter-based recovery on failure instead of silently propagating NaN.
Updated the redmaple data source URL in the documentation.

Install

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

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

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

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-qrjoint

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-qrjoint

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-qrjoint

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.
