Factor analysis: application of the absolute difference method in additive factor models

The peculiarity of economic analysis in modern conditions is a significant change in its tasks and functions, the emergence and development of new relevant directions. Under these conditions, attention to traditional issues of economic analysis, including its classical theoretical and methodological foundations, has somewhat weakened. Meanwhile, in the field of theory of economic analysis, one can find points that require separate explanations, justifications, and adjustments to the methodology. In particular, in our opinion, this applies to such an issue as factor analysis, and the application of its methods to calculate the influence of factors on the effective indicator in additive factor models. This question is considered in this article.
