Compute the F1 Score.
F1_Score(y_true, y_pred, positive = NULL)
Ground truth (correct) 0-1 labels vector
Predicted labels vector, as returned by a classifier
An optional character string for the factor level that
corresponds to a "positive" result
logreg <- glm(formula = vs ~ hp + wt,
family = binomial(link = "logit"), data = mtcars)
pred <- ifelse(logreg$fitted.values < 0.5, 0, 1)
F1_Score(y_pred = pred, y_true = mtcars$vs, positive = "0")
F1_Score(y_pred = pred, y_true = mtcars$vs, positive = "1")
