Assignment 2

Introduction: Predicting the status of a loan is an important problem in risk assessment. A bank or financial organization has to be able to estimate the risk involved before granting a loan to a customer. Data Science and predictive analytics play an important role in building models that can be used to predict the probability of loan default. In this project, we are provided with a data set loan_timing.csv containing 50000 data points. Each data point represents a loan, and two features are provided as follows:

a) The column with header “days since origination” indicates the number of days that elapsed between origination and the date when the data was collected.

b) For loans that charged off before the data was collected, the column with header “days from origination to charge-off” indicates the number of days that elapsed between origination and charge-off. For all other loans, this column is blank.

Project Objective: We would like you to estimate what fraction of these loans will have charged off by the time all of their 3-year terms are finished. Please include a rigorous explanation of how you arrived at your answer, and include any code you used. You may make simplifying assumptions, but please state such assumptions explicitly. Feel free to present your answer in whatever format you prefer; in particular, PDF and Jupyter Notebook are both fine. Also, we expect that this project will not take more than a week
