Parameter	Description
slopes or coefficients regression	This coefficient of the parameter shows the impact of that parameter on the dependent variable and this impact is called the elasticity of the dependent variable toward independent variables for example if the coefficient for independent parameter A is estimated 0.6 it means that the 1% increase in the A causes 0.6% increase in the dependent parameter.
Sensitivity index of the ANN model	This index shows the sensitivity or the dependence amount of the dependent variable toward the independent parameters for example if the dependent variable's sensitivity toward the parameter A be estimated 0.6% it means that the 1% increase in the parameter A causes a 0.6% increase in the amount of the dependent variable.
