ABSTRACT

A method for Combining statistical-based QSAR predictions of two or more binary classification models is presented. It was assumed that all models were independent. This facilitated the combination of positive and negative predictions using a quantitative weight of evidence (qWoE) procedure based on Bayesian statistics and the additivity of the logarithms of the likelihood ratios. Anterior studies combined more than one prediction but used arbitrary strengths for positive and negative predictions. In our approach, the combined models were validated by Determining the sensitivity and specificity values, which are performance metrics that are a point of departure for obtaining values ​​that measure the weight of evidence of positive and negative predictions. The developed method was experimentally applied in the prediction of Ames mutagenicity. The method achieved a similar accuracy to that of the experimental Ames test for this endpoint when the overall prediction was determined using a combination of the individual predictions of more than one model. Calculating the qWoE value would redueix the requirement for expert knowledge and decrease the Subjectivity of the prediction. This method could be applied to other endpoints such as developmental toxicity and skin sensitisation with binary classification models.
