R Documentation

Compute the top decile lift and plot the lift curve

plotLift plots the commonly used lift curve by ordering the data by the predictions, and computing the proportion of positives for each bucket.

plotLift(predicted, labels, cumulative = TRUE, n.buckets = 10, ...)

`predicted`	A numeric vector with the classifier's predicted scores / probabilities
`labels`	An integer vector containing binary labels with values 0,1
`cumulative`	boolean. Should the cumulative lift curve be plotted or not?
`n.buckets`	scalar. How many buckets should be used. One can use more buckets with large datasets
`...`	additional parameters to the `plot` function
