01Prinsip

Eight principles

P1

Famili indeks, bukan satu skor monolitik

NXS-GRX (data kanonis, asal-usul, dan risiko) menerbitkan dua puluh indeks domain, empat indeks pilar, satu komposit, dan enam instrumen. Komposit tidak pernah ditampilkan tanpa setiap pilar dan domain di sampingnya, dan tidak ada dimensi independen yang diciutkan secara diam-diam.

P2

Kelas dengan interval, tidak pernah tabel peringkat

Setiap nilai memiliki interval 90% dari analisis Monte Carlo atas normalisasi, bobot, imputasi, dan agregasi. Negara ditempatkan dalam kelas risiko dengan probabilitas kelas yang dinyatakan; halaman mencantumkan negara menurut nama atau kode, tidak pernah menurut nilai.

P3

Tidak ada data bukan berarti nol

Masukan yang hilang ditampilkan sebagai hilang, masukan yang diimputasi diberi tanda, dan nilai ditahan bila cakupan berada di bawah batas minimum metode. Profil kosong, sumber yang tidak tersedia, dan nol hasil pengamatan ditampilkan secara berbeda.

P4

Setiap nilai merujuk ke sumbernya

Setiap nilai membawa rilis sumber, lisensi, waktu pengambilan, versi metode, dan rantai transformasinya (W3C PROV). Koreksi di mana pun merambat ke setiap nilai yang bergantung dan dicatat secara publik.

P5

Yang terukur, dimodelkan, dan dipersepsikan dipisahkan

Glif status memisahkan masukan teramati, dilaporkan, diperkirakan, disimpulkan, prakiraan, simulasi, skenario, dan pakar. Sinyal persepsi membentuk instrumennya sendiri dan tidak pernah dicampur ke dalam risiko terukur.

P6

Sistemik sejak rancangannya

Risiko mandiri dan risiko yang disesuaikan dengan keterkaitan dilaporkan berdampingan, dari jaringan ketergantungan bertipe di bidang perdagangan, keuangan, energi, pangan, infrastruktur, dan informasi.

P7

Dibatasi lisensi dan dapat direproduksi

Sumber masuk ke nilai publik hanya jika lisensinya mengizinkan penggunaan tersebut; nilai yang ditahan dihitung, tidak disembunyikan. Metode, jalur kode, seed, dan digest diterbitkan per rilis sehingga setiap nilai dapat dihitung ulang.

P8

Informasi, bukan otoritas

NXS-GRX adalah informasi riset dan analitik risiko. NXS-GRX bukan pemeringkatan, klasifikasi resmi, peringatan, tolok ukur, atau nasihat, dan tidak pernah memutuskan atas nama suatu lembaga.

02Alur

Sumber ke profil

Every indicator declares its place on the risk chain and its polarity, so aggregation never mixes directions silently.

Pillars and domain indices

Pillar values are expert-weighted geometric means of their domain indices (equal weights in the baseline, recorded per release); a pillar needs two thirds of its domains, otherwise it is withheld.

05Kelas

Classes and intervals, never league tables

A class is printed with its probability (share of Monte Carlo draws inside the class). Below 60% the adjacent class is printed too (for example High, 54% · Very high, 41%). Fixed bounds keep classes comparable across editions; intervals show when two countries cannot be told apart. Lists are ordered by name or code.

06Konstruksi

Ten construction steps

The steps follow the OECD/JRC handbook on composite indicators and the statistical audit practice of the JRC Competence Centre on Composite Indicators, referenced for method only.

Theoretical framework Risk chain from hazard to outcome; four pillars; twenty index domains; explicit polarity and risk component for every indicator.
Data selection indicator definitions with SDMX-compatible keys, crosswalks to source code lists, evidence class A–E and the licence register.
Missing data Flagged imputation only at IND layer (dimension mean, indicator median, multiple imputation); modelled share capped per composite; coverage minimum two thirds.
Multivariate analysis Correlation structure, principal components and Cronbach’s alpha per sub-index; incoherent components are re-specified before release.
Normalisation Min–max with fixed goalposts, percentile rank or identity on native 0–10 scales; skew and kurtosis treatment (winsorisation, log) above |skew| 2 and kurtosis 3.5.
Weighting and aggregation Equal or expert weights recorded per composite; geometric, arithmetic, Mazziotta–Pareto, product or geometric-complement aggregation as each definition declares; floor 0.1 before geometric means.
Uncertainty and sensitivity At least 1,000 Monte Carlo runs over the declared alternatives; 90% intervals, class probabilities and Sobol indices published with every release.
Back to the data Driver decomposition to indicator level; every value opens to its inputs, sources and transformation chain.
Links to other indicators Published crosswalks and correlation checks against established indices, used as validity evidence, never as inputs to be re-weighted.
Visualisation and dissemination Classes and intervals, never league tables; machine access through API, SDMX keys, tiles and bulk files; corrections and versions public.
07Release

One edition, run as a workflow

An edition is a run: the evidence cut freezes, sources pass the licence gate, 451 indicators are computed for 195 profiles, 1,000 draws give the intervals, and two approval gates stand before anything is published.

08Aggregation

Five aggregation shapes

Try them on the fiscal and public debt index: switch the aggregation and watch the class and interval move.

Aggregation Apa yang dilakukannya Domain indices using it
geometric Weighted geometric mean after a floor of 0.1: partial compensation, so weakness in one component cannot be fully offset by strength in another. Risiko fiskal dan utang publik · Bahaya fisik iklim · Risiko ketahanan air · Risiko keamanan kesehatan · Kerentanan sosial-ekonomi · Risiko ketahanan energi · Kerapuhan infrastruktur · Risiko siber · Kurangnya kapasitas penanggulangan
Mazziotta–Pareto Mean adjusted by the spread across components (non-compensatory): unbalanced profiles read as riskier than balanced ones with the same mean. Risiko stabilitas keuangan · Risiko kerawanan pangan · Risiko konflik
arithmetic Weighted arithmetic mean: full compensation, used where components are substitutes. Risiko ketergantungan eksternal · Keterpaparan transisi iklim · Tekanan lingkungan · Tekanan pengungsian · Kelemahan tata kelola · Risiko konsentrasi teknologi
geometric complement Complement of the geometric mean of complements: any single high exposure lifts the index, as for multi-hazard exposure. Keterpaparan multibahaya
product Product of normalised components: risk exists only where all components are present, as for space-weather exposure. Keterpaparan cuaca antariksa

09Missing data

Tidak ada data bukan berarti nol

Imputation happens only at the indicator layer and is always flagged: dimension mean, indicator median or multiple imputation, as each definition declares. Each composite caps the share of its weight that may rest on modelled or imputed inputs and withholds its value below its coverage minimum. Coverage is published as a vector per country and indicator, never as a single complete flag; fragile and small-island states are where gaps cluster, so their coverage is shown first.

19Revisions

Revisions and corrections

Methodology carries a semantic version; a change that breaks comparability is back-cast where inputs allow, and a correction propagates to every dependent value with a public log entry.

20Vintages

Point-in-time vintages and validation metrics

Validation follows the composite-indicator audit practice of the JRC and the early-warning literature (Kaminsky and Reinhart 1999; Alessi and Detken 2011).

Vintages

Nothing is overwritten

Every edition and every correction is a vintage with its snapshot, frozen inputs and method version. A past value stays retrievable as it was published, so any study can be rerun on the information available at the time.

Revisions

Revisions are measured

Each indicator publishes its revision record between vintages, as the mean absolute revision and its direction, so a reader can see which inputs move after first release.

Stabilitas

Rank reversal is tested

Adding or removing a country or an indicator must not reorder the others beyond the uncertainty already reported; the test is part of each edition’s uncertainty analysis.

Peringatan dini

Signals are back-tested

Forecast and trigger instruments are scored out of sample, in pseudo real time: AUROC with its interval, noise-to-signal ratio, usefulness against the cost of a missed event, and the Brier score for probabilities.

Comparability

Breaks are declared

A method change that breaks comparability is back-cast where inputs allow; otherwise the series carries a declared break and comparisons across it are refused.

Lab

Try the methods yourself

The Index Lab runs these construction and validation methods on your own numbers in the browser.

21Reproducibility

Recompute any value

Each release publishes definitions, method versions, code paths, random seeds and content digests; every kernel is tested against hand-derived golden values.
