score_halfnormal: Half-Normal Score

Description Usage Arguments Value Examples

View source: R/score_halfnormal.R

Description

Score is approximately: ∑{\#[res_i ≤q simres_{i,j}] - n } with the distinction that each element of sum is also scaled to take values from [0,1].

res_i is a residual for i-th observation, simres_{i,j} is the residual of j-th simulation for i-th observation, and n is the number of simulations for each observation. Scores are calculated on the basis of simulated data, so they may differ between function calls.
