Lending Club Data AnalysisLending Club (LC) data, LC is a peer-to-peer online lending platform. It is the world’s largest marketplace connecting borrowers and investors, where consumers and small business owners lower the cost of their credit and enjoy a better experience than traditional bank lending, and investors earn attractive risk-adjusted returns.

Project ObjectivePredict if lenders can
make default payment for the borrowed loan
Predict Interest Rate to be charged on the
loan amount
Predict if the loan will be approved for an interest rate of 10%
or below
End Users : Borrowers And Lenders

Data Exploration
For each loan, over 100 characteristics are recorded in the table.
We have explored Data Dictionary from the Lending Club website, which gives us the information about the features in the dataset. We explored the dataset using r and Tableau to understand and find correlations between different features.

Model Evaluation for Loan Status• We have compared over all accuracy, recall, precision, ROC
curve and confusion matrix• If this model is to help lenders avoid bad loans, the true positive
rate must be much more robust
