Lift Formula Classification

Lift Formula Classification. Predict the probability y = 1 (positive) using the lr model and arrange the observation in the. The lift curve uses this returned probability to asses how our model is performing, and how well it is identifying the positive (1s or sick patients) or negative (0s or healthy patients) instances of our dataset.the data.

Sort the data based on the predicted probability in descending order. The classification variable should have two levels.
