01Principios

Eight principles

P1

Una familia de índices, no una puntuación monolítica

NXS-GRX (datos canónicos, procedencia y riesgo) publica veinte índices de dominio, cuatro índices de pilar, un compuesto y seis instrumentos. El compuesto nunca aparece sin todos los pilares y dominios a su lado, y ninguna dimensión independiente se agrega de forma silenciosa.

P2

Clases con intervalos, nunca clasificaciones

Cada valor lleva un intervalo del 90 % obtenido de un análisis de Monte Carlo sobre la normalización, las ponderaciones, la imputación y la agregación. Los países se sitúan en clases de riesgo con una probabilidad de clase declarada; las páginas enumeran los países por nombre o código, nunca por valor.

P3

Sin datos no es cero

Un dato de entrada que falta se muestra como faltante, un dato imputado se señala y un valor se retiene cuando la cobertura cae por debajo del mínimo del método. Un perfil vacío, una fuente no disponible y un cero observado se muestran de forma distinta.

P4

Cada valor remite a su fuente

Cada valor lleva su versión de fuente, su licencia, su hora de obtención, su versión de método y su cadena de transformación (W3C PROV). Una corrección en cualquier punto se propaga a todos los valores dependientes y se registra públicamente.

P5

Lo medido, lo modelizado y lo percibido se mantienen separados

Los glifos de estado distinguen datos observados, informados, estimados, inferidos, pronosticados, simulados, de escenario y de experto. Las señales de percepción forman su propio instrumento y nunca se mezclan con el riesgo medido.

P6

Sistémico por construcción

El riesgo independiente y el riesgo ajustado por acoplamiento se presentan uno junto al otro, a partir de redes de dependencias tipadas en comercio, finanzas, energía, alimentación, infraestructura e información.

P7

Sujeto a licencia y reproducible

Una fuente entra en un valor público solo cuando su licencia admite ese uso; los valores retenidos se contabilizan, no se ocultan. Los métodos, rutas de código, semillas y resúmenes se publican en cada versión para que cualquier valor pueda recalcularse.

P8

Información, no autoridad

NXS-GRX es información de investigación y analítica de riesgos. No es una calificación, una clasificación oficial, una alerta, un índice de referencia ni un consejo, y nunca decide por una institución.

02Cadena de procesamiento

De la fuente al perfil

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

03Pilares

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.

05Clases

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.

06Construction

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 Lo que hace 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. Riesgo fiscal y de deuda pública · Amenaza física climática · Riesgo de seguridad hídrica · Riesgo de seguridad sanitaria · Vulnerabilidad socioeconómica · Riesgo de seguridad energética · Fragilidad de la infraestructura · Riesgo cibernético · Falta de capacidad de afrontamiento
Mazziotta–Pareto Mean adjusted by the spread across components (non-compensatory): unbalanced profiles read as riskier than balanced ones with the same mean. Riesgo de estabilidad financiera · Riesgo de inseguridad alimentaria · Riesgo de conflicto
arithmetic Weighted arithmetic mean: full compensation, used where components are substitutes. Riesgo de dependencia externa · Exposición a la transición climática · Presión ambiental · Presión de desplazamiento · Debilidad de la gobernanza · Riesgo de concentración tecnológica
geometric complement Complement of the geometric mean of complements: any single high exposure lifts the index, as for multi-hazard exposure. Exposición multiamenaza
product Product of normalised components: risk exists only where all components are present, as for space-weather exposure. Exposición al clima espacial

09Missing data

Sin datos no es cero

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.

BorradorCalculadoLigado a la evidenciaRevisadoAprobado para su publicaciónPublicadoCorregidoSustituido
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.

Estabilidad

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.

Alerta temprana

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.
