CART (Classification and Regression Tree) uses the Gini index method to create

### Gain and Lift charts are used to evaluate performance of classification model. They measure how much better one can expect to do with the predictive model comparing without a model. It's a very popular metrics in marketing analytics. It's not just restricted to marketing analysis.

3. Gain and Lift charts. Gain and Lift chart are mainly concerned to check the rank ordering of the probabilities. Here are the steps to build a Lift/Gain chart: Step 1 : Calculate probability for each observation Step 2 : Rank these probabilities in decreasing order. Step 3 : Build deciles with each group having almost 10% of the observations. Gain and Lift Charts: Gain or lift is a measure of the effectiveness of a classification model calculated as the ratio between the results obtained with and without the model. Gain and lift charts are visual aids for evaluating performance of classification models.
