Abstract
In volatile financial markets, the exclusive reliance on point forecasts proves inadequate for representing the complexity and uncertainty of future dynamics. To address this limitation and enhance the reliability of risk assessment and decision-making, the literature has advanced a broad spectrum of uncertainty quantification methodologies, incorporating both traditional statistical inference and contemporary machine learning approaches. This paper mainly reviews the machine learning and statistical methods commonly used in financial risk prediction: for example, prediction interval estimation of ensemble learning methods such as random forest; Traditional confidence interval construction and bootstrap method; Bayesian regression (such as BART) and posterior prediction based on MCMC; Application of Monte Carlo simulation in risk measurement. We discuss from the perspective of method theory and literature application, without involving specific empirical results. Finally, the advantages, disadvantages and future development directions of these methods are compared and analyzed.
