Data mining tools have emerged as one of the most prominent modern methods in recent years. The significance of this research originates from the difficulties faced by businesses. Current methods can improve companies' capacity for financial forecasting, thereby reducing risk and bolstering financial stability. Using the regression equation to analyze time series data is one of the data mining instruments. It aids in predicting financial failure and equips businesses with the information necessary to make crucial decisions. Data mining and financial forecasting were first described to accomplish the research objectives.
