The MECS Global Market Assessment for electric cooking uses 40 indicators from publicly available sources to represent the viability of a scale up of electric cooking in 130 ODA recipient countries.

Summary of the methodology:
    1) Identification of factors which contribute to viability of electric cooking.
        a. Long- and short-listing potential factors by research team.
        b. Stakeholder engagement to review list by GMA steering group and others.
    2) Construction of the GMA database
        a. Searching for viable datasets to represent the identified factors.
        b. Datasets which are deemed viable become indicators.
    3) Data processing
        a. Imputation by regression of indicators with inadequate global coverage using proxy datasets.
        b. Assignment of upper and lower bounds to indicators.
        c. Imputation by grouping to achieve 100% complete database.
        d. Normalisation according to bounds (so 0 = worst and 1 = best for all indicators).
    4) Producing final score and rankings
        a. Produce agreed weightings (representing relative importance of each indicator).
        b. Multiplication of indicator data by weightings to produce scores for each indicator.
        c. Indicator scores summed for each country to produce final score.
