破产机器学习 破产数据研究的目的是为给定数据确定预测破产的最佳分类方法。 破产数据是从COMPUSTAT收集的1980年至2000年的数据,其中有5436个观察值和13个变量。 9个基于会计的变量和1个市场变量是:R1:WC / TA,营运资金/总资产R2:RE / TA,未分配利润/总资产R3:EBIT / TA,息税前利润/总资产R4:ME / TL,权益/总负债的市场价值R5:S / TA,销售/总资产R6:TL / TA,总负债/总资产R7:CA / CL,流动资产/流动负债R8:NI / TA,净收入/总资产R9:破产成本,对数(销售)R10:市值,对数(绝对(价格)*流通股数/ 1000) 对于本研究,由于没有明显的破产趋势,因此可以假定可以将多年来的数据汇总在一起并进行研究。 在这13个变量中,其中一个是“ DLRSN”-一种表示默认值的分类变量,即预测的因变量。 总体而

The original purpose of the book was to present a unified theoretical and conceptual framework for statistical modelling in a way that was accessible to undergraduate students and researchers in other fields. The second edition was expanded to include nominal and ordinal logistic regression, survival analysis and analysis of longitudinal and clustered data. It relied more on numerical methods, visualizing numerical optimization and graphical methods for exploratory data analysis and checking model fit. The third edition added three chapters on Bayesian analysis for general- ized linear models. To help with the practical application of generalized linear models, Stata, R and WinBUGS code were added. This fourth edition includes new sections on the common problems of model selection and non-linear associations. Non-linear associations have a long history in statistics as the first application of the least squares method was when Gauss correctly predicted the non-linear orbit of an asteroid in 1801. Statistical methods are essential for many fields of research, but a widespread lack of knowledge of their correct application is creating inaccu- rate results. Untrustworthy results undermine the scientific process of using data to make inferences and inform decisions. There are established practices for creating reproducible results which are covered in a new Postface to this edition.
