Claim 14:
15. A computer-implemented method of estimating individual components that contribute to an aggregated statistic, comprising:
inputting data in K trials, and inputting predictors of overall rate of contribution to the aggregated statistic;
inputting contribution data of the K trials, the contribution data indicating total contribution T between a start and an end of each of the K trials;
dividing each of the K trials into time or space segments of length measure λi;
grouping the segments from the K trials into a number N of clusters, the clusters being defined in accordance with ranges of at least one of the predictors of rate of contribution, each cluster being defined as having a weight Wj which is to be determined;
using an algorithm to build a model predicting the weight Wj based on solving a system of equations, one per trial, each equation equating a known total contribution T of a trial with a sum of a known length measure of each segment in the trial multiplied by the weight for a cluster into which the segment was grouped;
for each segment, assigning the predicted weight applied to the cluster in which the segment was grouped as a predicted rate of contribution Yi; and
storing a segment identifier (ID) with an indication of the predicted rate of energy use Yi to thereby allow determination of a prediction of contribution for the aggregated statistic based on collective processing of one or more segments among the segments grouped into the clusters.
