  "Description": "Comprehensive instrumental variables and generalized\nmethod of moments (GMM) estimation with automatic diagnostics,\ninspired by the 'Stata' command 'ivreg2' of Baum, Schaffer, and\nStillman (2003) <doi:10.1177/1536867X0300300101> and Baum,\nSchaffer, and Stillman (2007) <doi:10.1177/1536867X0800700402>.\nSupports two-stage least squares (2SLS), limited information\nmaximum likelihood (LIML), Fuller, k-class, two-step efficient\nGMM, and continuously updated (CUE) estimators. Provides\nclassical, robust, cluster-robust, heteroskedasticity- and\nautocorrelation-consistent (HAC), and Driscoll-Kraay standard\nerrors. Reports weak identification, underidentification,\noveridentification, and endogeneity tests at estimation time.\nAll outputs are verified against 'Stata' within tight numerical\ntolerances.",

    "message": "Open the post-0.1.0 development cycle and expand the DESCRIPTION acronyms\n\nCRAN accepted ivreg2r 0.1.0 on 2026-07-21, so the released tree is now fixed and the repository needs a version number that distinguishes it from CRAN's copy. DESCRIPTION moves to 0.1.0.9000, the conventional development suffix, which sorts above 0.1.0 and below any future release.\n\nThe CRAN reviewer asked that the next update expand every acronym in the Description text. GMM, 2SLS, LIML, and HAC are now written out at first use, and the CUE expansion is reordered so the words precede the abbreviation. The generated package help page is regenerated from the same field.\n\nThe README installation block leads with install.packages(\"ivreg2r\") and keeps install_github() below as the development-version route. NEWS.md gains a development heading recording the Description change.\n\nR CMD check --as-cran is clean: 0 errors, 0 warnings, 0 notes.\n\nCo-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>\n",
