Component analysis (statistics)

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Component analysis is the analysis of two or more independent variables which comprise a treatment modality.[1][2][3] It is also known as a dismantling study.[4]

The chief purpose of the component analysis is to identify the component which is efficacious in changing behavior, if a singular component exists.[2]

Eliminating ineffective or less effective components may help with improving social validity, reducing aversive elements, improving generalization and maintenance, as well as administrative efficacy.

It is also a required skill for the BCBA.[5]
