Compute the log loss for models with binary outcome.
Usage
performance_logloss(model, ...)
Arguments
model
Model with binary outcome.
...
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.
