In ModelMetrics: Rapid Calculation of Model Metrics

Description

True Positives / (True Positives + False Positives)

Usage

ppv(actual, predicted, cutoff = 0.5)

Arguments

actual	A vector of the labels
predicted	A vector of predicted values
cutoff	A cutoff for the predicted values

Examples

data(testDF)
glmModel <- glm(y ~ ., data = testDF, family="binomial")
Preds <- predict(glmModel, type = 'response')

ppv(testDF$y, Preds, cutoff = 0)
precision(testDF$y, Preds, cutoff = 0)
