对环比发展速度变异指标的探讨

Discussion of Varition Index about Chain Development Speed

变异指标在静态变量数列中的应用已相当广泛和普及,但动态数列特别是环比发展速度动态数列的平均发展速度的代表性,就观察其变异程度,评价其平均发展速度的代表的目的而言,仍可采用标准差系数。

Although application of cariation index in static variable number arrangement is widespread and popular The common recognition is not obtained of representativeness about average development speed in dynatic number arrangement,especially in dynamic number arrangement of chain development speed and of its variation degrees. As far as variation degees, evaluation of representativeness about average development speed are concerned, standard difference coefficients can be still used.
