The invention relates to a method for detecting a fault when operating a system comprising a certain number (M) of data records. Each data record (16) encompasses a number (N) of input data (18a,b) and at least one piece of target data (18c) that correlates with said input data. Each piece of input data (18a,b) takes exclusively values lying within a value range (W<SUB>n</SUB>), and the input data (18a,b) thus span a certain input data range (20). The inventive method comprises the following steps: - at least one of the value ranges (W<SUB>n</SUB>) is subdivided into intervals (I<SUB>k ,n</SUB>) such that N-dimensional cells (Z) comprising the intervals (I<SUB>k,n</SUB>) as edge lengths are formed within the input data range (20); - one cell (Z) is selected as the cell (Z) that is to be tested; - a test criterion (42, 44, 48) for the target data (18c) of the data records (16) of the selected cell (Z) is determined from the values (F) of the target data (18c) of the data records (16); - each data record (16) of the selected cell (Z) whose value (F) of the piece of target data (18c) fails to meet the test criterion (42, 44, 48) is marked as faulty. |
