Changes in version 0.1.1 (2026-02-12)                  

Patch release addressing CRAN maintainer feedback.

Bug fixes

  - Suppressed misleading error message during package installation when
    'cmdstanr' is not available. Stan model compilation is now silently
    skipped with an informational note instead of an error-like message.

  - Removed SystemRequirements: CmdStan from DESCRIPTION. CmdStan is not
    required to install or check the package; it is only needed at
    runtime for model fitting.

                 Changes in version 0.1.0 (2026-02-10)                  

Initial CRAN release.

Features

Link Functions

  - 5 standard link functions: logit, probit, cloglog, loglog, cauchit
  - 6 flexible link functions with shape parameters:
      - t-link (df)
      - Aranda-Ordaz (lambda)
      - Symmetric Power (r, base)
      - log-gamma (lambda)
      - GEV (xi)
      - AEP (theta1, theta2)

Threshold Structures

  - flexible: Standard ordered thresholds (default)
  - equidistant: Equal spacing between thresholds
  - symmetric: Symmetric thresholds around zero

Prior Specification

  - Distribution-based API: prior(normal(0, 2.5), class = "b")
  - Support for normal, student_t, cauchy, gamma, and flat priors
  - Legacy API via clm_prior() for backward compatibility

Model Comparison

  - LOO-CV via loo()
  - WAIC via waic()

Diagnostics

  - diagnostics() for MCMC convergence checks
  - plot() with multiple types: trace, dens, hist, areas, intervals, acf

Prediction

  - predict() for class predictions
  - fitted() for probability predictions
  - posterior_predict() for posterior predictive samples
