modelimpact - Assess the Business Impact of Classification Models

Calculate and visualise the financial impact of using a classification model to prioritise or target cases. Although originally designed for customer churn, the same tools apply to many binary classification problems, including fraud detection, credit default, lead scoring and marketing response, upsell and cross-sell, and predictive maintenance. Provides cost, revenue, profit and return-on-investment curves as a function of the share of cases targeted, cumulative gains and lift, marginal profit per bin, and confusion-matrix based payoff across probability thresholds. Also includes 'ggplot2' 'autoplot()' methods and an interactive 'shiny' application for exploring the results.
