Factor Modeling 因子建模 - Machine learning provides a more general framework for financial modeling than its linear parametric predecessors, generalizing archetypal modeling approaches, such as factor modeling, derivative pricing, portfolio construction, optimal hedging with model-free, data-driven approaches which are more robust to model risk and capture outliers.^{[1]}This paper focuses on the problem of multi-factor modeling and reasoning about the trusted relationship between elements, and proposes an association probability analysis model based on multi-element fusion.

Finally, we end our article with a discussion of alternative forms of model specification that have become particularly popular recently: exploratory structural equation modeling (ESEM) and bifactor modeling.^{[1]}The present study with 2,273 students aimed to examine the factorial validity of the Anxiety Questionnaire for Students (AFS) by using the bifactor modeling framework, that is, contrasting a confirmatory factor analysis (CFA) model to an exploratory structural equation model (ESEM) and two bifactor models (B-CFA and B-ESEM).
