A method of correlating data in terms of non-dimensional variable groups is discussed. The method is based on Group Method of Data Handling (GMDH). An algorithm for the method is developed and an example of the algorithm''s application is discussed. The algorithm developed is convenient for correlating experimental data of complicated systems. It should be stressed that the application of the method necessitates many kind of heuristics through which the method shows the versatility in the application.
