Abstract:

Data dimension is decreased by using time order weighted averaging operator (TOWA) and time order weighted geometric averaging operator (TOWGA), then the minimal variability weighting vector method is introduced, which determines the minimal variability weighting vector under the given level of time orness. An example is also discussed to compare numerical results with entropy programming method and minimal variability weighting vector method, some conclusions are gained by comparison.
