Resumen:
  We show, on purely statistical grounds and without appeal to any physical model, that a power-law q-entropy Sq , with 0 < q < 1, can beq-entropy Sq , with 0 < q < 1, can be extensive. More specifically, if the components Xi of a vector X ?¸ RN are distributed according to a Gaussian probability distribution, the associated entropy Sq(X) exhibits the extensivity property for special types of correlation among the Xi . We also characterize this kind of correlation.
