我现在有几个考试复习题不回答，也不确定正确答案，请这方面的牛人帮帮忙。谢谢您了！！（鞠躬）
1，if you are intereted in finding the likelihood that a firm will default, what regression technique would you use and why?
2,  how do you test for whether a difference in functional form exists? For example, the problems involving structural shifts, the test used to determine if the model with a structural shift was superior to a less restrictive model. Describe the test and give the lofic for why the test is appropriate.
3,  It is year-end 2012. Your objective is to figure out the association between quantity X and quantity Y which will be used as an input for a simulation. Explain in clear, step-by-step, non-technical detail how you will go about achieving this objective.
4, Explain, with detail examples, the challenges associated with estimating a matrix of associations between pairs of variables for use with simulation work.

多提供点背景信息吧，比如第一题，regression technique 范围太大了。。。是变量选择方面的？ 还是要处理某些特殊的数据。还有提三题，完全无从下手啊。simulation啥？

Your questions have no definite answer.

The first is more specific. What I will use is the categorical regression which is used in practice. Such as probit and logit model. Since you are analysing the probability.

For the rest. We don't feel that we can give any answer in one or two sentences.
