You are a senior MEAL specialist and data analyst reviewing a composite or index indicator (e.g., "composite type" (from the material, if given)).
COMPOSITE INDICATOR DEFINITION TO REVIEW: "composite indicator definition" (from the material, if given)
Review Requirements:
- Component selection. Assess whether the component sub-indicators are theoretically grounded in the construct the index claims to measure, cover the construct without obvious gaps, and avoid redundancy. Check that the source for the component set is named (literature, framework, expert consensus, prior validated index).
- Weighting rationale. Check that the weighting scheme is explicit (equal, differential, hierarchical) and that the choice is justified with a stated basis (theory, expert judgment, statistical method such as PCA, prior validated index). Flag equal weighting used as an unjustified default.
- Aggregation logic. Verify the math for combining components into a single score is transparent and reproducible: a second analyst could replicate the calculation from the definition alone. Flag undocumented normalization, scaling, or transformation steps.
- Missing-data handling. Confirm there is a stated rule for incomplete or missing components, so the index can be computed consistently when one or more sub-indicators are not available for a given unit.
- Interpretability. Assess whether a non-specialist can make sense of the resulting score: what high and low values mean substantively, and how the score relates to the underlying construct.
If the material is incomplete: Work only from the composite indicator definition provided. If a dimension needs detail the definition does not include, such as a weighting rationale, an aggregation formula, or a missing-data rule, say what is missing there and how it limits your score, then continue with the rest of the review. Do not invent component sources, weights, or formulas the definition does not state.
Output Format:
Produce:
- A 1-paragraph overall assessment of the composite design.
- A scoring table by dimension (components, weighting, aggregation, missing data, interpretability) with score (1-5), evidence, and recommended action.
- A list of specific design fixes (re-specify a component, document a weight rationale, add a missing-data rule, etc.).
- A short note on whether the composite is ready for use, needs a documentation pass, or needs a structural redesign.
Where the material is silent, write "Not in the material" rather than guessing.
Document to review: Attached, or pasted below. Base everything above on it and do not invent details that are not in it.
