Scoring

All four metrics are dimensionless. The total score is the product of specificity, host distance and confidence.

0.333
Specificity
1 / the number of pathogens on the vector — this vector carries 3 pathogens in EPPO.
0.20
Host distance
1.0 = no shared hosts · 0.5 = shared family · 0.2 = shared genus · 0.0 = shared species.
0.50
Confidence (P-K)
K = confirmed vector (1.0), P = potential (0.5); both edges are multiplied.
0.033
Total
specificity × host distance × confidence
