@winm2m/react-stats-ui

React UI component for browser-based inferential statistics workflows, powered by @winm2m/inferential-stats-js.

Installation

npm install @winm2m/react-stats-ui @winm2m/inferential-stats-js

Peer dependencies:

• react ^18.2.0 || ^19.0.0
• react-dom ^18.2.0 || ^19.0.0

What the component provides

• Dataset management with IndexedDB (import XLSX, select/delete dataset, drag-drop upload zone).
• Analysis selection popover with current analysis display, grouped into 6 categories.
• Variable assignment UI with drag/drop, double-click assignment, and role-aware validation.
• 16 built-in analysis types (t-test, ANOVA, regression, clustering, factor/component methods, etc.).
• Auto-run queue execution when inputs change (analysis, role assignment, dataset, options).
• Worker lifecycle UX (signal indicator, loading state, error state, initial blocking overlay).
• Result area with APA table rendering, JSON toggle, payload toggle, and formatted clipboard copy.
• Imperative external control API via React ref (runtime data injection, result panel visibility, APA clipboard copy, direct analysis calls).
• Two layout modes:
  • full: split control/result with resizable vertical divider
  • minimal: compact flow with slide-up result panel

Supported analyses

• Frequencies
• Descriptives
• Crosstabs
• Independent-Samples T-Test
• Paired-Samples T-Test
• One-Way ANOVA
• Post-hoc Tukey HSD
• Linear Regression (OLS)
• Binary Logistic Regression
• Multinomial Logistic Regression
• K-Means Clustering
• Hierarchical Clustering
• Exploratory Factor Analysis
• Principal Component Analysis
• Multidimensional Scaling
• Cronbach Alpha

Basic usage

import * as React from "react";
import { StatsWorkbench } from "@winm2m/react-stats-ui";

export function App() {
  return (
    <div style={{ width: "100vw", height: "100vh" }}>
      <StatsWorkbench />
    </div>
  );
}

Component API

StatsWorkbench props:

• className?: string
• style?: React.CSSProperties
• initialAnalysis?: AnalysisKind (default: "frequencies")
• layoutMode?: "full" | "minimal" (default: "full")
• language?: "en" | "ar" | "zh" | "fr" | "ru" | "es" | "ko" | "ja" | "vi" (default: "en")
• showDatasetPopover?: boolean (default: true)
• minimalAutoShowResultEnabled?: boolean (default: true)
  • When false in minimal layout, auto-show is disabled and the Auto show result switch is hidden.
• analysisExecutor?: (payload: AnalysisPayload) => Promise<unknown>
• onResult?: (result: AnalysisResult) => void

StatsWorkbench ref (StatsWorkbenchControl):

• injectData({ rows, columns?, id?, name? })
  • Injects runtime analysis data without writing to IndexedDB.
  • If columns is omitted, variable metadata is inferred from rows.
• clearInjectedData()
• executeAnalysis(method, inputWithoutData?)
• runFrequencies(inputWithoutData?)
• runDescriptives(inputWithoutData?)
• runCrosstabs(inputWithoutData?)
• runTtestIndependent(inputWithoutData?)
• runTtestPaired(inputWithoutData?)
• runAnovaOneway(inputWithoutData?)
• runPosthocTukey(inputWithoutData?)
• runLinearRegression(inputWithoutData?)
• runLogisticBinary(inputWithoutData?)
• runLogisticMultinomial(inputWithoutData?)
• runKmeans(inputWithoutData?)
• runHierarchicalCluster(inputWithoutData?)
• runEfa(inputWithoutData?)
• runPca(inputWithoutData?)
• runMds(inputWithoutData?)
• runCronbachAlpha(inputWithoutData?)
  • All 16 async wrappers call @winm2m/inferential-stats-js and always inject previously provided runtime data as data.
• setResultVisible(next) (minimal layout)
• toggleResultVisible() (minimal layout)
• setAutoShowResult(next)
• toggleAutoShowResult()
• getAutoShowResult()
• copyApaTable()

Example:

import * as React from "react";
import { StatsWorkbench, type StatsWorkbenchControl } from "@winm2m/react-stats-ui";

export function App() {
  const workbenchRef = React.useRef<StatsWorkbenchControl>(null);

  const runExternal = async () => {
    workbenchRef.current?.injectData({
      name: "runtime-dataset",
      rows: [
        { score: 10, group: "A" },
        { score: 12, group: "A" },
        { score: 14, group: "B" },
        { score: 15, group: "B" }
      ]
    });

    await workbenchRef.current?.runTtestIndependent({
      variable: "score",
      groupVariable: "group",
      group1Value: "A",
      group2Value: "B",
      equalVariance: true
    });

    await workbenchRef.current?.copyApaTable();
  };

  return (
    <>
      <button onClick={() => void runExternal()}>Run external t-test</button>
      <div style={{ width: "100vw", height: "90vh" }}>
        <StatsWorkbench ref={workbenchRef} layoutMode="minimal" />
      </div>
    </>
  );
}

Internationalization

The workbench includes built-in i18n via i18next + react-i18next.

Supported languages:

• en (English)
• ar (Arabic)
• zh (Chinese)
• fr (French)
• ru (Russian)
• es (Spanish)
• ko (Korean)
• ja (Japanese)
• vi (Vietnamese)

Coverage includes core UI labels, placeholders, role prompts, options labels, run-state messages, and result-view helper text.

Use language prop to set the active language:

<StatsWorkbench language="ko" />

Exports:

• StatsWorkbench
• AnalysisKind
• StatsWorkbenchProps
• AnalysisPayload
• AnalysisResult
• ExternalDataInput
• StatsWorkbenchControl

Execution behavior

• The workbench builds a payload and runs analysis when configuration is valid.
• Input changes are queued and processed sequentially.
• While running, duplicate execution is blocked.
• In minimal mode, result view is a slide-up panel.
• In minimal mode, result panel can be shown/hidden by UI toggle or external control.
• In minimal mode, multi-item role updates (for multi roles like variables/independentVariables) use a manual Play trigger shown in Role Assignment when execution is valid.

Result behavior

• APA table view is default.
• More menu contains:
  • APA Table <-> JSON toggle
  • Show/Hide API payload
• Copy button copies APA tables in both plain text and HTML format for paste into Excel/Word (formatted headers/borders).

Demo page

docs/demo.html demonstrates CDN usage and local dev build usage:

• Live demo: https://winm2m.github.io/react-stats-ui/demo.html

• ?dev=true loads /dist/index.js

• otherwise loads published package from npm via ESM CDN

• includes demo selectors for:

  • Theme: light / dark
  • Layout: full / minimal

Storybook

Scripts:

npm run storybook
npm run build-storybook
npm run test
npm run test:ci

CI runs typecheck, test:ci, and build automatically on push/PR via .github/workflows/ci.yml.

Story file: src/stats-workbench.stories.tsx

Interactive controls include:

• Section Layout: full / minimal
• Language: en / ar / zh / fr / ru / es / ko / ja / vi
• Theme: light / dark / custom
• Background
• Background Transparent
• Text
• Border
• Major
• Minor
• Warning
• Error
• Info
• Rounded Edges

Theme behavior:

• Selecting light or dark applies a preset palette.
• Editing any themed color while light/dark is active switches mode to custom.

Notes

• Internal UI uses Radix primitives and lucide-react icons.
• Worker URL can be controlled via window.__WINM2M_INFERENTIAL_WORKER_URL__.
• The component is designed to fill the parent container.
