Technique for determination of an exception in multi-dimensional data

摘要

A technique for determination of an exception in multi-dimensional data is provided. The method determines an expected value for a set of cells of the multi-dimensional data by means of an ANOVA based method. A residual for each cell of the set of cells is then determined. Scaling of the residuals is then carried out, and the scaled residuals are then compared with a threshold value for determination of the exception.
