Methods for estimating the seasonality of groups of similar items of commerce data sets based on historical sales data values and associated error information

摘要

A set of data is received containing values associated with respective data points, the values associated with each of the data points being characterized by a distribution. The values for each of the data points are expressed in a form that includes information about a distribution of the values for each of the data points. The distribution information is used in clustering the set of data with at least one other set of data containing values associated with data points.
