méretüktl

Méretüktl is a coined term in statistical and comparative analysis used to describe methods that adjust measurements for size effects to allow fair comparisons between entities of different sizes.

Origin and terminology: The term is formed from the Hungarian word méret (size) and a theoretical suffix -üktl; it has no widely established etymology beyond this coined usage and is primarily encountered in Hungarian-language texts on scaling and normalization.

Definition: In broad terms, méretüktl covers approaches that transform an observed metric M into a size-adjusted metric M* by scaling with a size measure S and an exponent α, such that M* = M / S^α. The exponent α is chosen to reflect the expected allometric relation between M and S.

Method: Steps: select a representative size variable S, determine α via empirical fitting or theory, compute M*, and use M* for cross-group comparisons, regression analyses, and index construction. It is closely related to normalization and allometric scaling.

Applications: Used in ecology to compare metabolic rates across species of different body masses, in urban studies to compare economic indicators across cities of varying population, and in marketing to assess performance relative to market size.

Limitations: Choice of size variable and exponent can strongly influence results; mis-specification can introduce bias; it does not capture all structural differences beyond size.
