Some criteria

  • MSD = Mean signed deviation (can be negative)
  • MAD = Mean absolute deviation (≥0)
  • RMSD = Root mean square deviation (≥0)

EWSD (Element-Wise signed deviation)

Plot the probability density function of the deviation distribution.

BSS (Brier Skill Score)

The BSS corresponds to the ratio between modelled evolution and measured evolution.

BSS

  • Zm : target bottom (reference file)
  • Zt : modelled bottom (test file at specified frame)
  • Z0 : initial bottom (test file at first frame)
BSS Quality
1.0 - 0.5 Excellent
0.5 - 0.2 Good
0.2 - 0.1 Reasonable
0.1 - 0.0 Mediocre
< 0.0 Bad
