To develop a model, the contribution of the both anion and cation parts are considered. This would help to study the effect of structural variation of both ionic segments on the desired physical property.
Genetic Function Approximation is applied for model's parameter selection (molecular descriptors) and its development. Consequently, a simple linear predictive model with satisfactory results quantified by the following statistical parameters: absolute average deviations (AAD) of the predicted properties from existing experimental values by the GFA linear equation: 1.98%, linear correlation coefficient squared (R2): 0.9657 and Root Mean Square: 4.3 K.
