| Abstract | A relatively new concept of stochastic 3-dependence as, between others, taking place in reliability modeling of three or more component systems, is described and analyzed. In that context we described the 3-dependence phenomena for k-variate probability distributions (k ≥ 3) of random vectors, say (X1, … ,Xk). First we introduce the concept for the k = 3 cases and then we extend it to an arbitrary higher dimension k = 4, 5, … . Some of the models with 3-dependence and r-dependence (for r ≥ 4), present, are known in literature but with no explicit reference to this stochastic phenomenon, while this was exhibited in this paper. Additionally, in this paper, one new model is proposed. This is a three-variate "modified normal density" with 3-dependence described. Notice, that 3-dependence is not present in classical 3-variate nor any k-variate ( k ≥ 4) normal distribution. Several versions of the obtained modified normal model were proposed too.
