PerformanceScoreCard

Python script to automate the performance of scorecard. The script creates the charts for the following charts and profiles:

• ROC, AUC, KS, Score@KS
• Cumulative Gains Chart
• Precision Recall Chart
• Deciles Profile
• Confusion Matrix
• Histogram of classes
• Quadratic weighted kappa
• Linear weighted kappa
• Kappa
• Mean quadratic weighted kappa
• Weighted mean quadratic weighted kappa

Functions

The fuctions can be called from another python script to get individual performances.
