JRC QSAR Model Database
(Q)SAR Model Reporting Format Inventory
In the regulatory assessment of chemicals (e.g. under REACH), Quantitative Structure Activity Models (QSAR) are playing an increasingly important role in predicting properties for hazard and risk assessment. This implies both a need to be able to identify relevant QSARs and to use them to derive estimates and/or have access to their precalculated estimates. To help meet these needs, the JRC QSAR Model Database is established and freely accessible through http://qsardb.jrc.ec.europa.eu/qmrf The QSAR Model Reporting Format (QMRF) is a harmonised template for summarising and reporting key information on QSAR models, including the results of any validation studies. ... -

QSAR Qualitative Validation
Qualitative validation of QSAR models
The purpose of this program is to verify the ability of the QSAR/Pharmacophore model to distinguish significantly between the two classes (i.e. active and inactive molecules). It is based on calculation of different qualitative validation parameters such as sensitivity, specificity, precision, accuracy, and F-measure. -

QSAR Data Pretreatment
To remove the constant and highly correlated descriptors based on user
Before performing the actual chemometric analysis in QSAR, the raw data is usually pretreated due to following reasons: 1. To remove those descriptor whose values remains more or less constant for all compounds, since they only add computing time without contributing much to the results. 2. To reduce collinearity among the descriptors thereby preventing data over-fitting and aids in improving the prediction performance of the model. -

MLR Y randomization
This test is performed to check the robustness of the QSAR model
This test is performed to check the robustness of the QSAR model by building several random models via shuffling the dependent variables, while keeping the independent variables as it is. The resultant random models are expected to have significantly low r^2 and q^2 values for several trials, to pass the test. Another parameter, cRp^2 is also calculated, which should be more then 0.5 for passing this test. -
