In this paper, a probabilistic signal processing method which is possible to give any methodological suggestion to the measurement method of correlative and/or accumulative effect in compound environment of sound, light and electromagnetic (abbr. EM) waves is discussed. In order to extract various types of latent interrelation characteristics between waved environmental factors of different kind leaked from the actually operating VDT, an extended regression system model reflecting hierarchically not only linear correlation information of the lower order but also nonlinear correlation information of the higher order is firstly introduced. Then, through estimating each regression parameter of this model, some evaluation methods for predicting a whole probability distribution form from one to another are newly proposed. Finally, the validity and effectiveness of this proposed method are experimentally confirmed too by applying it to the actually observed data leaked by a VDT with some television games in the room of an actual working environment.
