Model Evaluation Tools — Analysis Lab · consolidated app gallery

Eight self-contained prototypes for exploring, visualizing, and interpreting MET-style verification output — seven views plus the STAT Ingest bridge that parses real MET output. All run the same shared verification math (lib/met-stats.mjs), are dependency-free, and work fully offline.

How to run

01

Client-side Verification Wrapper

Theme 01 · Client-side wrapper

Documented MET verification math run entirely in the browser: live 2×2 contingency table, full categorical + continuous suites, a per-stat MET-fidelity formula table, a SQL-like query panel, and drag-drop CSV.

02

Stat Explorer

Theme 02 · Modern interaction

Direct-manipulation explorer with explicit Metric / Dimension / Filter / Facet vocabulary driving three cross-filtered linked views (brushable line plot, sortable table, faceted small multiples). Aggregates the correct ratio-of-sums way.

03

Novel Plotting & Visuals

Theme 03 · Novel plotting

A gallery of four interactive verification visuals: a Performance Diagram (CSI contours + bias rays), a Reliability + Sharpness panel with Brier decomposition, a draggable threshold scrubber, and MODE-style object verification.

04

Guided Verification Journey

Theme 04 · Modernization

A cohesive 4-step diagnostic journey (Overview → Error vs lead → Categorical skill → Reliability) with a per-view provenance panel, shareable URL-hash sessions, and a deterministic rule-based narrator grounded in the on-screen numbers.

05

Map-native Spatial Verification

Theme 03 · Spatial maps

A pannable/zoomable Canvas error field over a synthetic gridded domain with forecast/obs/error layers, named region masks, per-mask continuous + categorical MET stats, hover readout, and a brush box. Shows ratio-of-sums vs mean-of-ratios on screen.

06

Ensemble Verification Views

Theme 03 · Ensemble

Four coherent ensemble diagnostics over one synthetic dataset — rank (Talagrand) histogram, spread-skill, probabilistic reliability + sharpness + Brier decomposition, and CRPS — all driven by a single under→calibrated→over dispersion knob.

07

Volumetric 3D — Metric Cube

Theme 03 · 3D / volumetric

An orbitable, tiltable 2.5D Canvas height-field rendering a verification metric over a lead × threshold × region cube, with scrubbable slicing planes, a synced 2D slice panel, hover-to-raw-counts, and a 12-metric live switcher.

08

STAT Ingest — real-data bridge

Round 3 · Real MET .stat ingestion

The keystone parser: header-driven, version-tolerant ingestion of real MET .stat / per-type .txt / MODE output (CTC, CTS, SL1L2, CNT, PCT, PSTD, PRC, RHIST, ECNT, ORANK) feeding the shared lib. Paste or drop a real file; parsed PCT bins reproduce the paired PSTD Brier decomposition exactly. Ingested strings rendered injection-safe.
