3. Nonlinear Regression Question (a) Describe a concrete example where nonlinear regression methods might be used to answer a financial, economic, business, or social science question. (b) Describe specific datasets you can use to answer the question and example you've described above. Include links to datasets not discussed in class. (c) Write down the regression model you have in mind for the example you've describe above. (d) Describe each of the model's variables. Which model parameter is important for your example? (e) What are the standard assumptions that are sufficient for you to consistently esti- mate your model's parameter of interest? (f) Explain each assumption's interpretation in the contex of your specific example and model. (g) Explain how one of the assumptions might not hold for your specific example and model. (h) What statistical test or parameter can you use to answer your example's question? (i) Write down the test's null and alternative hypotheses. (j) Explain the meaning of the null and alternative hypotheses in the context of your example. (k) Estimate the model you've described above. Report the results below. You can report results using a screenshot. (1) Interpret the results for the model you've estimated in the previous question. What do the results mean for the example and question you've described
