dx_f1 | R Documentation |
Calculates the F1 score from a confusion matrix object with an option to include bootstrapped confidence intervals. The F1 score is the harmonic mean of precision and recall.
dx_f1(cm, detail = "full", boot = FALSE, bootreps = 1000)
cm |
A dx_cm object created by |
detail |
Character specifying the level of detail in the output: "simple" for raw estimate, "full" for detailed estimate including 95% confidence intervals. |
boot |
Logical specifying if confidence intervals should be generated via bootstrapping. Note, this can be slow. |
bootreps |
The number of bootstrap replications for calculating confidence intervals. |
Depending on the detail
parameter, returns a single numeric value of
F1 or a data frame with the F1 and its confidence intervals.
dx_fbeta()
, dx_f2()
for other F-beta scores.
cm <- dx_cm(dx_heart_failure$predicted, dx_heart_failure$truth,

detailed_f <- dx_f1(cm)
