For example, if a conceptually important item only cross loads on a factor to be dropped, it is good to keep it for the next round. Drop the items, and run a confirmatory factor analysis asking the program to give only the number of factors after dropping the uninterpretable and single-item ones.
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables.

Exemplar Theory is often contrasted with prototype theory, which proposes another method of categorization.Recently the adoption of both prototypes and exemplars based representations and categorization has been implemented in a cognitively inspired artificial system called DUAL PECCS (Dual Prototypes and Exemplars based Conceptual Categorization System) that, due to this integration, has ...

It is a hierarchy within groups that ascribe them to different levels of privileges. [1]
In this method, seven groups of bipolar adjective scales corresponded to seven types of nouns so the method was thought to have the object-scale symmetry (OSS) between the scales and nouns for evaluation using these scales. For example, the nouns corresponding to the listed 7 factors would be: Beauty, Power, Motion, Life, Work, Chaos, Law.
