Multiclass Probability Predictions
Details
This data frame contains the predicted classes and
class probabilities for a linear discriminant analysis model fit
to the HPC data set from Kuhn and Johnson (2013). These data are
the assessment sets from a 10-fold cross-validation scheme. The
data column columns for the true class (obs), the class
prediction (pred) and columns for each class probability
(columns VF, F, M, and L). Additionally, a column for
the resample indicator is included.

# `obs` is a 4 level factor. The first level is `"VF"`, which is the
# "event of interest" by default in yardstick. See the Relevant Level
# section in any classification function (such as `?pr_auc`) to see how
# to change this.
