The prediction was based on dataset comprised from the following descriptors: "Skin sensitisation"
Estimation method: Taking highest mode value from the 5 nearest neighbours
Domain logical expression:Result: In Domain

("a" and ("b" and "c" ) )

Domain logical expression index: "a"

Similarity boundary:Target: c1(C(O)(c2ccc(N(C)C)cc2)c2ccc(N(C)C)cc2)ccc(NC)cc1
Threshold=80%,
Dice(Atom pairs)

Domain logical expression index: "b"

Parametric boundary:The target chemical should have a value of log Kow which is >= 0.317

Domain logical expression index: "c"

Parametric boundary:The target chemical should have a value of log Kow which is <= 7.98
