Аннотация:A new variant of the CLT is established for random fields defined on R^d which are strictly stationary, with a finite second moment and weakly dependent (comprising cases of positive and negative association). The summation domains grow in the van Hove sense. At the same time indices of observations form more and more dense grids in these domains. Thus the effect of combining two scaling procedures is studied. A statistical version of this CLT is also proved. Some stochastic modeles in radiobiology based on dependent functional subunits are discussed as well.
