Using Statistical Methods to Screen for Earnings Manipulation and Corporate Fraud
摘要
This chapter explores statistical methods that may be used for screening for corporate fraud and earnings manipulation. It briefly discusses time series analysis, cross-sectional analysis and TSCS analysis for corporate fraud detection. Then the chapter details practical models like the Beneish M-Score, Montier C-score, Sloan Accruals Ratio, etc., explaining their calculations and interpretations. It also introduces Benford’s Law, a principle used to detect anomalies in financial data, and the AB-Score and ABF-Score, which build upon Benford’s Law and the Dechow F-Score. Finally, the chapter touches briefly on other statistical tools like the Z-Score, Chi-square test, Runs test, and multivariate analysis as building blocks for corporate fraud detection.
