Aptula, A.O.; Jeliazkova, N.G.; Schultz, T.W.; Cronin, M.T.D. The Better Predictive Model: High q2 for the Training Set or Low Root Mean Square Error of Prediction for the Test Set?. QSAR Comb. Sci. 2005, 24, 3, 385–396.

Published: Villu Ruusmann (2012-05-23)

Abstract: The process of validation of computational models (e.g., QSARs) may become the most important step in their development. Different requirements for the reliability and predictability of QSAR models have been described in the literature. Despite these formal recommendations there are few practical rules as to when to cease adding variables to a QSAR (i.e., what ...

Published: Villu Ruusmann (2012-05-23)

Abstract: A QSAR analysis has been carried out of the toxicity of 47 mono-substituted nitrobenzenes to the aquatic ciliate Tetrahymena pyriformis. The single most important parameter was the logarithm of the apparent partition coefficient (logD) at pH 7.35. 2- and 3-derivatives yielded an excellent correlation of toxicity with log D, Swain-Lupton field parameter and ...

Published: Villu Ruusmann (2012-05-23)

Abstract: The aim of this study was to develop quantitative structure-activity relationships for the toxicity to Tetrahymena pyriformis of 30 substituted poly-hydroxylated benzenes. Physico-chemical descriptors for the expression of free radical formation, associated with the OH moiety on the aromatic ring, were calculated. These included one-electron equilibrium constants ...

Published: Villu Ruusmann (2012-05-23)

Abstract: There are many issues relating to the use of Quantitative Structure–Activity Relationships (QSARs) to make predictions for regulatory purposes. Among those issues, characterization of models and the development of suitable tools to determine applicability domains rank as the more important. With regard to aquatic toxicology, QSARs for acute effects (e.g., ...
