Estimated value profiling

The strategy table, strat_df, can be used to maximize the estimated portfolio value and minimize expected loss. Extending this table and creating some plots can be very helpful to this end.

The strat_df data frame is loaded and has been enhanced already with the following columns:

Column	Description
Num Accepted Loans	The number of accepted loans based on the threshold
Avg Loan Amnt	The average loan amount of the entire test set
Estimated value	The estimated net value of non-defaults minus defaults
