• Key Concepts: 
  A gain chart is a visual representation of the performance of a predictive model. It is used to compare the performance of different models and to identify the best model for a given task. The chart is divided into two parts: the x-axis represents the predicted probability of an event occurring, and the y-axis represents the actual probability of an event occurring. The gain chart shows how well the model is able to predict the outcome of an event. 
  
  How to use it: 
  In Predictive Studio, gain charts are used to evaluate the performance of predictive models. To create a gain chart, select the “Gain Chart” option from the “Analyze” menu. Select the model you want to evaluate and click “Run”. The gain chart will be displayed in a new window. 
  
  Tips & Tricks: 
  When evaluating a model using a gain chart, look for models that have a high area under the curve (AUC). A high AUC indicates that the model is able to accurately predict outcomes with high accuracy. Additionally, look for models that have a high lift value, which indicates that the model is able to accurately predict outcomes with higher accuracy than random chance.
