Timing diagram
First, the total population of Table (end) of the annual data series {Xt}, full of energy consumption (kg of standard coal) annual data series {Yt} are drawn timing diagram, in order to observe the annual population data series {Xt} and national annual energy consumption data sequence {Yt} is stationary, by EVIEWS software output is shown below.
Figure of the total population (end) sequence timing diagram
Figure universal life energy consumption (kg of standard coal) sequence timing diagram
Figure is a sequence {Xt} the timing diagram, Figure is a sequence {Yt} of the timing diagram.
Two figures show both the total population (end) or universal life energy consumption (kg of standard coal) index showed a rising trend, the total population of the annual data series {Xt} and national annual energy consumption data sequence {Yt} not smooth, the two may have long-term cointegration relationship.
. Data smoothing
()Sequence Logarithm
Figures and by the intuitive discovery data sequence {Xt} and {Yt} showed a significant growth trend, a significant non-stationary sequence. Therefore, the total population of first sequence {Xt} and universal life energy consumption (kg of standard coal)
