Global AD Index

AD index = 1

Explanation: the predicted compound is into the Applicability Domain of the model.

Similar molecules with known experimental value

Similarity index = 0.874

Explanation: only moderately similar compounds with known experimental value in the training set have been found.

Accuracy of prediction for similar molecules

Accuracy index = 0.074

Explanation: accuracy of prediction for similar molecules found in the training set is good.

Concordance for similar molecules

Concordance index = 0.32

Explanation: similar molecules found in the training set have experimental values that agree with the predicted value.

Maximum error of prediction among similar molecules

Max error index = 0.142

Explanation: the maximum error in prediction of similar molecules found in the training set has a low value,

considering the experimental variability.

Conclusions:
Predicted LogPow for (1R,2R,3S,4S)-1-(1,3-dithian-2-yl)pentane-1,2,3,4-tetrol is -0.79.
