actuarialfitdist 0.2.3 (CRAN documentation candidate)

• Shorten the package title and add a standard loss-modeling reference in DESCRIPTION.
• Rewrite help-page return-value descriptions and important argument explanations.
• Clarify ground-up observation censoring versus post-deductible payment caps.
• Document deterministic analytic plotting as the default and simulation as optional.
• Add installation instructions and a reproducible release-check procedure.
• No changes to likelihood, optimization, plotting, or factor-calculation code.

actuarialfitdist 0.2.2 (numerical-stability update)

• Fit a zero-intercept nested anchor before estimating a free scaling intercept. Reject an apparently converged free-intercept fit if its log likelihood is materially worse than the nested solution.
• Retry Gamma/Burr optimizations from multiple shape starts, report optimizer_attempts, reject inadmissible final fits, and avoid pathological near-zero/astronomical shape values that cause catastrophic floating-point cancellation.
• Compute Burr log-density and log-survival using stable log1p-exp expressions.
• Construct deterministic fitted severity-plot probabilities from conditional log-survival ratios rather than 1 - F(d) to avoid loss of tail precision.
• Candidate fitting reports failed families as missing AIC/BIC rather than rewarding degenerate fits.
• Add tests for heavy-censoring, large-scale covariates, nested intercept likelihood, Burr degeneracy, and extreme-tail plot survival.
• These changes prioritize fit validity over the fastest possible fitting time. Source is distributed for independent R CMD check; CRAN checks still required on a machine with R.

actuarialfitdist 0.2.1

• Corrected roxygen2 help text so mathematical expressions are not interpreted as cross-reference links. Qualified utils::head/tail and made ggplot data-mask references explicit for clean R CMD check.

• Corrected invalid reserved-word argument names in all-fixed-parameter fitting branches in fit_severity() and fit_spliced_severity().

• Automatic numerical parscale for estimated scale intercepts; explicit optimizer overrides preserved, including in spliced models.

• Candidate comparison now includes individual runtimes, optimizer evaluation counts and convergence codes.

• Reuse repeated deductible/scaling term probabilities within each ordinary likelihood evaluation.

• Candidate and single-fit plots default to deterministic censoring/truncation-aware bin/CDF summaries rather than simulating large portfolios. method = "simulation" retains the previous option.

• fit_plot_data() and candidate_plot_data() support output = "plot_ready"; scaling_plot_data() exposes the exact long plot data.

• User-facing plot axis-label sizes, angles and explicit tick breaks; 45-degree tick rotation for faceted candidates.

• Exact rejection simulation for inverse Gaussian draws conditional on a deductible, avoiding most per-row inverse-CDF root searches.

• New regression tests and documented benchmark script; updated README/vignette/examples.

actuarialfitdist 0.2.0 (development)

• Documentation-only CRAN check cleanup: unique S3 aliases, correct plotting helper documentation association, and wrapped candidate usage lines.

• Optional deductible and censoring-limit columns for single, candidate and spliced fits.

• One-pass anomaly screening, warnings, original-position excluded_rows, and reason table excluded_details; invalid_rows = "error" available.

• Splice threshold search reports eligible body/exact-tail counts and explicit rejected-candidate reasons; configurable minimum uncensored tail observations.

• Vectorized analytic limited expected values for exponential, Weibull, gamma and lognormal families; batched severity factor grids, plus paired scenario mode.

• Log10 severity axes and xlim controls; candidate overlays/facets using observation-aware simulated claim data.

• Expanded quick-start, worked candidate vignette, and API examples.

• The package source is provided for local R checks. Its CRAN status is not certified in an environment without R.

actuarialfitdist 0.1.0

• Numerical warnings from invalid optimizer trial points are now handled internally; such points receive a penalized likelihood while invalid final fits still fail explicitly.

• Initial release.

• Fits common actuarial severity distributions to ground-up losses with deductible truncation and limit censoring.

• Supports optional linear severity scaling, likelihood weights, fixed parameters, candidate comparison, and spliced body-tail models.

• Generates limited expected severities, LERs, ILFs, deductible factors, combined rating factors, and valuation-adjusted expected payments.

• Includes simulation-based goodness-of-fit diagnostics, scaling diagnostics, layer diagnostics, Hessian inference, and basic bootstrap support.

• 0.2.1 source maintenance: resolved candidate plotting default argument handling within lapply() and consolidated roxygen2 source-of-truth maintenance for help pages, NAMESPACE, package docs, and S3 print registration.
