tnc: Calculate the true negative count of a vector of predicted...
| tnc | R Documentation |
Calculate the true negative count of a vector of predicted probabilities against a binary outcome at a given threshold.
Description
Calculate the true negative count of a vector of predicted probabilities against a binary outcome at a given threshold.
Usage
tnc(preds, obs, thresh = 0.5)
Arguments
preds |
A vector of predicted probabilities. |
obs |
A vector containing the observed binary outcomes (0 or 1). |
thresh |
The probability threshold at or above which a prediction is considered to be positive. |
Value
The true negative count is the number of observations predicted as negative that are indeed negative
Examples
# Generate some predictions
predictions <- runif(1000)
# Generate some binary outcomes
observations <- sample(0:1, size = 1000, replace = TRUE)
# Calculate the true negative count
tnc(predictions, observations)
