【Abstract】 Considering the spacing interval i n primary accumulating generating of primitive data sequence, the basic theory and approach for establishing a GM(1,1) model for non-equidistant sequence are presented, Examples show that the approach raised is definite in concept, conve nient in calculation, good in fitting and precise in prediction, thus providing a good solution to the problems of fitting and prediction in establishing models for non-equidistant sequence.更多还原
