Description

Compute the accuracy classification score.

Usage

Accuracy(y_pred, y_true)

Arguments

y_pred	Predicted labels vector, as returned by a classifier
y_true	Ground truth (correct) 0-1 labels vector

Value

Accuracy

Examples

data(cars)
logreg <- glm(formula = vs ~ hp + wt,
              family = binomial(link = "logit"), data = mtcars)
pred <- ifelse(logreg$fitted.values < 0.5, 0, 1)
Accuracy(y_pred = pred, y_true = mtcars$vs)
