version 0.3.0 2026-03-30

New Features

• Comprehensive Econometric Correctness Test Suite: Added extensive validation tests covering likelihood derivation, parameter identification, standard error computation, and parameter recovery across various sample sizes and true parameter configurations

Bug Fixes

• Chi-square GOF test: Fixed argument handling for chi-square goodness-of-fit test
• Expected values formula: Corrected expected values computation in model fitting

Testing

• Simulation helpers: Added helper-simulation.R with reusable functions for parameter recovery testing
• Expanded test coverage: 612 tests (up from ~275 in v0.2.2), 7 skipped (extended tests)
• New test modules:
  • test-econometric-formula-derivation.R: Validates likelihood formula components
  • test-econometric-identification.R: Tests parameter identification conditions
  • test-econometric-likelihood.R: Verifies likelihood computation correctness
  • test-econometric-parameter-recovery.R: Monte Carlo parameter recovery validation
  • test-econometric-se-validation.R: Standard error computation verification

version 0.2.2 2025-12-15

Validation System Modernization

• Complete migration to checkmate: Replaced all manual input validation with robust checkmate assertions
• Enhanced validation utilities: Added comprehensive validation helper functions in utils-validation.R
• Standardized error messages: All validation errors now use consistent checkmate format
• Improved code quality: Eliminated all manual stop() calls and :: namespace patterns
• Dependency optimization:
  • Added checkmate dependency for robust input validation
  • Removed goji dependency by implementing internal zero1 function
• Test suite updates: Updated all test expectations to match new validation patterns
• Documentation improvements: Enhanced validation function documentation with proper @importFrom declarations

Development Workflow Improvements

• Local code coverage: Replaced Codecov.io with simple local coverage reporting
  • Added make coverage command for quick coverage analysis
  • Created Makefile for common development tasks
  • Removed external Codecov dependency and badge
• Fixed CRAN URL: Updated to canonical CRAN package URL format

version 0.2.1 2024-12-15

Infrastructure & Modernization

• Added comprehensive GitHub Actions CI/CD workflows for R CMD check, test coverage, and pkgdown
• Updated minimum R version requirement to 4.0.0
• Modernized code patterns:
  • Replaced T/F with TRUE/FALSE throughout
  • Updated logical operators to use || for scalar comparisons
  • Removed deprecated stringsAsFactors arguments
  • Added explicit parameters to mapply() calls
• Enhanced package metadata in DESCRIPTION
• Improved .gitignore and .Rbuildignore patterns
• Re-enabled and configured lintr for code quality checks
• Updated pkgdown configuration URLs

version 0.2.0 2017-05-XX

• Consistent support for input data format (with potential for d for ‘don’t know’).
• Person level adjustments for LCA and standard correction
• Explain logic for Rsolnp priors and allow people to pass different priors
• Standard output and nomenclature for stnd_cor and lca_cor, including option for s.e.
• Extensive linting, expect_lint_free passes
