METHOD FOR ESTIMATION OF ORDER-BASED STATISTICS ON SLOWLY CHANGING DISTRIBUTIONS

摘要

A computer-implemented method for estimation of order-based statistics on slowly changing distributions of data stored on a computer. An initial set of data is converted to an initial histogram based representation of the data set's distribution. New or removed data is converted into a new histogram separate from the initial histogram. The new histogram is combined with the initial histogram to build a combined histogram. Percentiles and order-based statistics are estimated from the combined histogram to provide analysis of a combination of the initial set of data combined with the new or removed data.
