Current Situation and Existing Problems of Factor Analysis Method

Abstract

Factor analysis is an important analytical method in psychology, medicine, economics, statistics, management and accounting. It is also widely used in various fields of social practice. This paper analyzes the history and development of factor analysis. It can be found from many teaching materials and social cases that factor analysis has many problems in the spread of knowledge in teaching materials and the practical application of society due to the defects in the theories and methods of factor analysis and difference analysis. The author believes that the fundamental reason lies in the fact that there is no scientific explanation for the difference formed by the interaction of various factors in the factor product equation of factor analysis. It is not only unscientific, correct and unfair to calculate the influence difference of factors, which can be used to evaluate the responsibility of the subject of economic activities and correct the deviation of experimental activities. The purpose of this paper is to discover and put forward problems on the premise of combing the application status of factor analysis and difference analysis, so as to lay a solid foundation for the subsequent discussion of "new methods of factor analysis and difference analysis". It is a prelude to the derivation of correct factor analysis and difference analysis methods.
