Fitting effect of theoretical model, 18-order polynomial, and double exponential model.

Evaluation parameters	Theoretical model	18-order polynomial	Double exponential model
SSE	24.64	22.01	0.35
𝑅-square	0.9852	0.9868	0.9999
Adjusted 𝑅-square	0.9849	0.9839	0.9997
RMSE	0.504	0.5213	0.0588

SSE: the sum of squares due to error; 𝑅-square: coefficient of determination; adjusted 𝑅-square: degree-of-freedom adjusted coefficient of determination; RMSE: root means squared error.
