Assignment Type: Individual
1.Consider the corporate bankruptcy prediction problem, and the list of variables in Appendix A. These variables are currently used to predict the probability of corporate failure for a firm, using annual financial and market data. Recommend additional variables, which are likely to be associated with the prediction of corporate bankruptcy and hence likely to improve the predictive power of the machine learning models. You should outline new variables that can be created from the existing variables (such as financial ratios), as well as external data sources you can collect from different Big Data sources. Justify why you believe they would be appropriate explanatory variables.

2.Recommend and discuss methods of exploratory data analysis that you would undertake to understand and visualize the data. Explain and motivate your choices.
3.Provide a summary analysis of the predictive performance of the CART model outlined in Appendix B, and an analysis of which variables contributed most to the model’s predictive power. Interpret the CART decision tree.
4.Compare results of the gradient boosting model outlined in Appendix C. Describe and explain any difference in model performance. Identify the role and impact of predictor variables in the CART and gradient boosting models.
5.Outline how the model/(s) can be embedded into a business or accounting process, to facilitate or inform decision-making. You may choose any appropriate business or accounting process.
