here, for data screening method: “no” refers to the model developed by the initial dataset obtained from NIST; “post” means that the dataset used to build the model is consistent with “no”, but only the data points selected under the pre-screening rules are used for calculatingQ 2. “pre” refers the model with the dataset after data pre-screening
3.4.3. Comparison with references
The results of comparison between this work and other literatures are detailed in Table 7. The significant difference from other works is that our work has a wider range of datasets and varying pressure conditions. Different from our previous studies and other groups, this work expanded the types of ILs and the number of relevant data points on the basis of increasing the pre-screening process for data points. Thus, the lnη (T ,P ,I )-QSPR model is slightly less accurate than our previous studies, however, it is more robust than the previous models, because this model has gone through a rigorous LOIO-CV model validation method. In addition, the modelling process kind of uses only the topology of the ILs, which has the advantage of simple, fast and efficient preliminary calculations of η .
