Half-Normal Score
Description
Score is approximately:
with the distinction that each element of sum is also scaled to take values from [0,1].
is a residual for i-th observation,
is the residual of j-th simulation
for i-th observation, and
is the number of simulations for each observation.
Scores are calculated on the basis of simulated data, so they may differ between function calls.

Examples
dragons <- DALEX::dragons[1:100, ]
# fit a model
model_lm <- lm(life_length ~ ., data = dragons)
# create an explainer
lm_audit <- audit(model_lm, data = dragons, y = dragons$life_length)
# calculate score
score_halfnormal(lm_audit)
