Nonconformity measure used by default in the class ConformalRegression to calculate nonconformity scores (alpha).
StandardMeasure
implements the following nonconformity measure:
alpha = |obs - pred| / pred_error
where alpha is the nonconformity measure,
obs is the observed value,
pred the predicted value with a point prediction model,
and pred_error is the error in prediction predicted with an error model.
See conformal
for further information about how to derive individual confidence intervals.

A numeric vector with the nonconformity scores (alpha).
