Usage

as_scores(distribution, y)

Scores derived from a predictive CDF

Arguments

Argument	Description
distribution	A distribution vector (see dist_shash).
y	Observed values, recycled against distribution.

Value

A tibble of centiles, Z-scores, tails, residuals, and log densities. Tails are evaluated in log space so that z = 8, 10, 40 remain distinct. There is no abnormality column.

Examples

as_scores(distributional::dist_normal(0, 1), c(-2, 0, 2))
