In the present case, logistic modelling approach may be
regarded as a complementary approach for forecasting the
medium- to long-term natural gas demand in China. Logistic modelling
approach is used to express the life-long process and has
been widely applied to demonstrate the growth process in different
fields in general [21–24] and natural gas forecasting in particular
[25–27]. Logistic modelling approach has the ability to capture
historical trend of the data pattern and precisely forecast the future
values. It is believed that optimal estimation of the parameters of
logistic models can greatly enhance the forecasting precision.
