  family = binomial(link = "logit")
)

explainer_lm <- DALEX::explain(lm_model, data = german[, -1], y = y_numeric)

fobject <- fairness_check(explainer_lm,
  protected = german$Sex,
  privileged = "male"
)


cm <- choose_metric(fobject, "TPR")
plot(cm)

rf_model <- ranger::ranger(Risk ~ .,
  data = german,
  probability = TRUE,
  num.trees = 200
)


explainer_rf <- DALEX::explain(rf_model, data = german[, -1], y = y_numeric)
