@@ -0,0 +1,248 @@+# Changelog++All notable changes to this project will be documented in this file.++The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),+and this project adheres to [PVP](https://pvp.haskell.org/) versioning.++## [Unreleased]++## [0.1.0.0] - 2026-05-19++First public release on Hackage.++### Added (130: HPotfire Vega-Lite migration foundation)+- `Hanalyze.Viz.PlotConfig`: `PlotConfig` moved out of `Viz.Core` and gained+ optional fields `plotColorScheme` / `plotFacetColumn` / `plotLegendPos`.+ `Viz.Core` re-exports both `PlotConfig` and `defaultConfig`, so existing+ imports keep working unchanged.+- `Hanalyze.Viz.PlotData`: source-agnostic intermediate+ `PlotData { pdNumeric, pdText, pdLength }` plus a `ToPlotData` adapter type+ class so future backends (DB / Parquet stream) can feed `*Spec` functions+ without taking a hard `dataframe` dependency. Hackage `dataframe` adapter+ lives in `Hanalyze.Viz.PlotData.DataFrame`.+- `Hanalyze.Viz.Core.vlJson :: VegaLite -> Text` — canonical JSON serialisation+ helper for downstream consumers (HPotfire `/api/viz`).+- `Hanalyze.Viz.Scatter.scatterSpec` / `Histogram.histSpec` /+ `Bar.barSpec` — `PlotConfig -> ... -> PlotData -> VegaLite` entry points.+ Scatter honours `plotColorScheme` / `plotFacetColumn` / `plotLegendPos`.++### Changed (130: Pareto Viz API)+- **BREAKING**: `Hanalyze.Viz.Pareto` rewritten on the `PlotData` convention.+ All public functions (`paretoScatter` / `paretoPair` / `parallelCoordinates`+ / `hypervolumeHistory` / `paretoCompare`) now take `PlotData` instead of+ `[Solution]`. Use the new `solutionsToPlotData :: [Text] -> [Solution] ->+ PlotData` helper to bridge from NSGA-II results.+- Demos `MaterialsMOODemo.hs` and `NSGADemo.hs` updated accordingly.++### Added (090: GLM diagnostics + predict SE)+- `Hanalyze.Model.GLM` exports the previously-internal helpers `Link`,+ `linkFnOf`, `glmDeviance`, `glmLogLik`, `glmVariance` (request 090-CD)+ so HPotfire can drop its local re-implementations.+- `glmPearsonResiduals` / `glmDevianceResiduals` for diagnostics+ (Q-Q / Scale-Location plots).+- `predictGlmEtaWithSE` and `predictGlmMuWithCI` (with `GlmPredictCI`+ record) for proper Wald CI on η and μ scales — replaces the+ `η ± 2·rse` approximation HPotfire has been using.++### Added (100: GLMM SE)+- `Hanalyze.Model.GLMM.glmmFixedSE :: Matrix -> Vector Int -> GLMMResult ->+ Vector Double` — exact LME (Gaussian) fixed-effect SE via+ block-structured `(Xᵀ V⁻¹ X)⁻¹`; non-Gaussian families fall back to a+ `σ² = 1` Gaussian approximation.+- `glmmBLUPSE :: Vector Int -> GLMMResult -> Vector Double` — posterior+ SD of random-intercept BLUPs `(1/σ²_u + n_j/σ²)⁻¹^½`. Suitable for+ forest plot whiskers.++### Fixed (P1: RFF OOM)+- `Hanalyze.Model.RFF.medianPairwiseDist`: rewrote with BLAS gram matrix+ (`Hanalyze.Stat.KernelDist.pairwiseSqDist`) + `Data.Vector.Algorithms.Intro.sort`+ on a flat `Vector`. The previous implementation built an `O(n²)` list of pair+ distances using `rows !! i` (each `O(i)`, so `O(n³)` walks total) and ran a+ naive list quicksort, which exploded space to many GB of thunks and OOM-killed+ WSL2 around `n=768` (e.g. inside `maximizeMarginalLikRBFMV`).+- `Hanalyze.Model.RFF.rbfKernelMat`: rewrote as+ `LA.cmap (...) (KD.pairwiseSqDist x)`. The old nested list comprehension with+ `rows !! i / rows !! j` shared the same `O(n³)` shape and hit the same WSL2+ OOM via `logMarginalLikRBFMV`.+- Removed the file-local naive `qSort` from `RFF.hs`.+- New `bench-rff-oom` executable as a regression guard. Post-fix:+ `maximizeMarginalLikRBFMV` with a 3·2·2 grid runs at `n=768` in ~10 s and+ ~45 MiB peak residency (was OOM).++### Fixed (P4: Tier-2 O(n²) helpers in Preprocess)+- `Hanalyze.DataIO.Preprocess.dropMissingRows`: cache per-column Text+ `Vector` once instead of calling `tryColumnAsList` + @xs !! i@ inside+ the inner row loop. O(rows² × cols) → O(rows × cols).+- `Hanalyze.DataIO.Preprocess.sliceColumn` (`tryAs`): convert the+ column to a `Vector` once and use `unsafeIndex` instead of+ @xs !! i@ in a list comprehension. O(n²) → O(n).++### Fixed (P3: GC pressure / O(n²) helpers)+- `Hanalyze.Model.GP.buildKernelMatrix` (1D variant): rewrote with a+ flat `Storable.Vector` filled via `runST + MVector` instead of+ materialising the @|xs|·|xs'|@ lazy `[Double]` list that the old+ `(n><m) [..]` form created (~30 MB of cons cells at `n=768`, pure+ GC pressure). API is unchanged so the `Periodic` kernel keeps its+ signed-difference behaviour.+- `Hanalyze.Model.GLMM.buildGroups`: replaced `sort . nub` with+ `Set.toAscList . Set.fromList` (O(n log n) vs O(n²)). Important for+ grouping vectors with thousands of distinct group IDs.++### Fixed (P2: stray naive quicksorts)+- `Hanalyze.Model.Quantile.quantile`: replaced file-local naive list quicksort+ with `Data.List.sort` (mergesort, O(n log n) / O(n) space). Pivot-bias could+ push the old version to O(n²) space on adversarial inputs.+- `Hanalyze.Stat.Test.sortVec` and the file-local `qsort` used by+ `mannWhitneyManual`: same replacement (`Data.List.sort` /+ `sortBy (comparing fst)`). Both `qSort`/`qsort` definitions removed.++## [0.1.0.1] - 2026-05-14++Initial Hackage release. (Version 0.1.0.0 was uploaded only as a+candidate and never published; the multi-output GP API was rearranged+before publication — see below.)++### Multi-output GP — API のデフォルトを shared-HP に変更+- `Hanalyze.Model.MultiGP.fitMultiGP` / `fitMultiGPMV` の **挙動を sklearn 流+ shared-HP 版に置き換え**。1 回の HP 最適化で全 q 出力の合算周辺尤度を+ 最大化し、`Ky = K + σ_n² I` の Cholesky を再利用する (RBF 専用、+ `q > 1` で旧版比 ~q× 速い)。+- 旧来の per-output 独立 HP 版 (任意カーネル対応) は+ `fitMultiGPIndep` / `fitMultiGPMVIndep` に **改名**。+- 旧 `fitMultiGPMVSharedHP` は新しい `fitMultiGPMV` に統合済 (削除)。+- 既存ユーザーは `fitMultiGP kern ...` を `fitMultiGPIndep kern ...` に+ 置き換えれば従来の挙動を維持できる。++### LM diagnostics + Taguchi/Quality 拡張+- `Hanalyze.Model.LM.Diagnostics` (new module): inference and residual diagnostics+ for OLS — `ciTValue`, `lmStdErrors[Multi]`, `CoefStats` /+ `lmCoefStats[Multi]` (SE / t / two-sided p), `FStat` / `lmFStatistic`+ (whole-model F, follows R-style df1 = p − 1, df2 = n − p), `ICs` /+ `lmInformationCriteria` (R `lm()` convention with k = p + 1, σ counted),+ `hatDiagonal`, `standardizedResiduals`, `cooksDistance`,+ `predictorStdDevs`. Multi-output (Matrix p × q) is the canonical form;+ Vector wrappers cover q = 1.+- `Hanalyze.Design.Orthogonal.OAMetadata` + `listArraysWithSize`: structured+ metadata (name / runs / factors / levels / description) for the+ standard L4–L18 arrays.+- `Hanalyze.Design.Taguchi.SNDetails` + `snRatioWithDetails`: SN ratio bundled+ with sample mean / variance / N.+- `Hanalyze.Design.Taguchi.FactorEffectExt` + `factorEffectsTable`: factor-effect+ rows enriched with `feeRange` and `feeContribution`.+- `Hanalyze.Design.Quality.Capability` + `processCapability` /+ `processCapabilityUpper` / `processCapabilityLower`: Cp / Cpk for+ two-sided and one-sided spec limits.++### Performance (Phase 1-13)+- Build flags: added `-O2 -funbox-strict-fields` to all 75 stanzas (library ++ executables + tests) via the new `common opt` block.+- Strict data: enabled `{-# LANGUAGE StrictData #-}` on 22 hot-path modules+ (Optim.{NSGA,LBFGS,DE,CMAES,CMAESFull,SA,PSO,Common,BayesOpt,Acquisition,+ Pareto,NelderMead,LineSearch}, Model.{GLM,Regularized,RFF,GP,Kernel},+ Stat.{KernelDist,Cholesky}, MCMC.{HMC,NUTS}).+- INLINE pragmas on hot-path wrappers: `Hanalyze.Stat.Cholesky.{cholSolve,cholFactor,+ cholSolveWithFactor}`, `Hanalyze.Stat.KernelDist.{diagAB,rowDotsAB,rowSqNorms}`,+ `Hanalyze.Optim.Common.flipFor`, plus 9 polymorphic helpers in `Hanalyze.Stat.AD`.+- `Hanalyze.Stat.KernelDist.pairwiseSqDist` rewritten with `runST + Storable.Mutable`+ flat-index loop; massiv dependency removed from this hot path+ (16-26% speedup on KR/Gram benchmarks).+- `Hanalyze.Model.GLM.glmLogLik` switched from list-based `zipWith`+`sum` to+ `VS.zipWith`+`VS.sum` (~20% speedup on GLM_logit_n=10000).+- `Hanalyze.Model.GLM.irlsStep` weight/working-response computation switched from+ massiv `MA.map`/`MA.zipWith3` to `VS.map`/`VS.zipWith3`.+- `Hanalyze.Stat.ModelSelect.lmPosteriorLogLiks`/`glmPosteriorLogLiks` switched to+ the same `VS.zipWith`-based pattern (avoids per-sample `LA.toList`+ allocations).+- Benchmark infrastructure: added `bench-tasty` (focused tasty-bench+ micro suite) and `bench-profile` (profiling runner with+ `cabal.project.local: profiling-detail: late-toplevel`). Migrated+ `bench-regression` and `bench-kernel` to use the new+ `BenchUtil.timeitTasty` (adaptive iteration, 5% relative stdev) instead+ of fixed-N `timeit`.

Performance varies by domain: optimisation and small-to-medium MCMC workloads are often faster in these benchmarks, while large-scale ML/GLM workloads are currently slower than sklearn.++---++## Highlights++- **Haskell-native**: types catch many dtype/API mismatches; shape checks happen at runtime where needed+- **Algorithms in Haskell, BLAS for numerics**: hmatrix/BLAS/LAPACK powers linear algebra; no R/Stan/Python bridge+- **HTML reporting**: MathJax/Mermaid + Vega-Lite visualisations in one call; PNG/SVG export available for supported plots+- **Dirty-data defence**: 8 warning codes + auto-sniff (delim/header/encoding) + cleaning DSL+- **Hackage `dataframe`**: Polars-like DataFrame used directly; CSV native, Parquet/JSON support through `dataframe`++---++## Capabilities++Features grouped by category.
