Compute the log loss for models with binary outcome.
Usage
performance_logloss(model, verbose = TRUE, ...)
Arguments
model
Model with binary outcome.
verbose
Toggle off warnings.
...
Currently not used.
Value
Numeric, the log loss of model.
Details
Logistic regression models predict the probability of an outcome of
being a "success" or "failure" (or 1 and 0 etc.). performance_logloss() evaluates
how good or bad the predicted probabilities are. High values indicate
bad predictions, while low values indicate good predictions. The lower
the log-loss, the better the model predicts the outcome.
