Mapean

Mapean is a term that appears in a limited set of online and print sources, and there is no widely accepted definition. Because its usage is sparse and context-dependent, meanings attributed to mapean vary between authors. In speculative or fictional writing, mapean has been used as the name of a people, place, or language. In discussions of statistics or data analysis, mapean is encountered only as a mistaken variant of the acronym MAPE (mean absolute percentage error); this is not an established usage.

Etymology is uncertain; it may be a coined form combining map and -ean, or derived from a proper name in a particular work. As there is no consensus, readers should consult the original source to understand the intended meaning. It is not a term with a standard definition in major reference works. Related terms include map and mapping, and caution is advised to distinguish mapean from similarly spelled or related acronyms.
