Interpret the following output of Multiple discriminant analysis (MDA)
说明以下多重判别式分析的结果
Data was collected on two groups of firms. One group is considered to be bankrupted (0 category) and another group to be non-bankrupted (1 category). The result shows that three independent variables: Solvency, Age and Quick ratio are important to explain bankruptcy (dependent variable) among sample firms. Interpret the result of Eigenvalues, Cox & Snell,
Nagelkerke R Square R Square, Structure Matrix and Classification Results.
