Usage

This is a quick introduction to the lift curve function of the package:

library(helda)

data_training <- titanic_training
data_validation <- titanic_validation

model_glm <- glm(formula = "Survived ~ Pclass + Sex + Age + 
                 SibSp + Fare + Embarked",
                 data = data_training,
                 family = binomial(link = "logit"))

predictions <- predict(object = model_glm, 
                       newdata = data_validation, 
                       type = "response")

plot <- lift_curve(predictions = predictions, 
                   true_labels = data_validation$Survived, 
                   positive_label = 1)
