1. A computer-based method of clustering data sets comprising executing on a computer the steps of:
- receiving a first set of data containing a plurality of data points, each of which is expressed as a value and an associated error;
determining a distance between the first set of data and each of one or more other sets of data, where each of those other data sets contains a plurality of data points, each of which is expressed as a value and an associated error, the determining step including measuring each distance as a function, at least in part, of the error associated with one or more data points in each of the sets of data for which the distance is determined, including measuring each distance as a function of the value and the error associated with one or more data points in each of the sets of data for which the distance is determined, in which the distance is measured based on

Abstract
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.

13. A computer program product, stored on computer readable medium, that when executed on a processor, determines composite seasonality time-series, the processor coupled to a display, the computer program product comprising:
computer program code for receiving data that represents seasonality time-series for each of a set of retail items, the data also representing error information associated with data values for each of a series of time points for each of the items, wherein the error information is used to measure a distance as a function of the error information, wherein a distance is measured as a function of the data value and the associated error information, in which the distance is measured based on
