时点序列理论的缺陷修补

时态序列理论是统计学中不可或缺的重要理论,其中的难点内容当属时点序列理论.目前许多版本的统计学教材在论述时点序列时的普遍做法是在未给出或不恰当给出连续时点序列与间断时点序列之概念的前提下计算这2类序列的平均发展水平,说明现行时点序列理论的确存在缺陷,即没有对时点序列的连续性作出科学合理的界定.显然,弥补该缺陷的唯一办法就是正确设定时点序列的连续性判别准则,并且努力展示该准则的应用价值.

The remedy for defects of time point sequence theory

The theory of time sequence is an essential theory in statistics,and the difficult part of this theory is the time point sequence theory.In many current statistics textbooks,the general way of discussing time point sequence theory is to compute the average development level of continuous time point sequence and intermittent time point sequence without providing or improperly giving their concepts,and to discuss the defects in current time point sequence theory without scientifically defining the theory’s continuity.The only way to make up the deficiency is to reasonably formulate the criterion of continuous time point sequence and try to present its application value.
