First, we establish the inequalities related to the upper bound for the probability of the sum of a random number of random variables satisfying certain conditions. More specifically, in Theorem 1, these variables are assumed that get values on a bounded interval and in particular, are setting under m-dependence assumption instead of the usual independence, where independence is merely the specific case of m-dependence when m equal to 0. For a random index with a familiar distribution, it is possible to proceed to make reasonable estimates for the expected terms on the right-hand side of the two inequalities in Theorem 1 to obtain Chernoff-Hoeffding-style bounds. Those bounds will be employed to prove that there is a weak law of large numbers for the sequence of m-dependent random variables correspondingly and the convergence rate is exponential. Next, in Theorem 2, we had chosen the Poisson distributed index as a typical for presentation. Finally, this theorem is illustrated through an image which is constructed by simulated values of 1-dependent variables. Here, the way that we have applied to create a 1-dependent sequence from an independent sequence that it is likely will help readers understand more about m-dependence structure.

In this article, we research some conditions for strong law of large numbers (SLLNs) for weighted sums of extended negatively dependent (END) random variables under sublinear expectation space. Our consequences contain the Kolmogorov strong law of large numbers and the Marcinkiewicz strong law of large numbers for weighted sums of extended negatively dependent random variables. Furthermore, our results extend strong law of large numbers for some sequences of random variables from the traditional probability space to the sublinear expectation space context.

In this work, we prove a weak law and a strong law of large numbers through the concept of [Formula: see text]-product for dependent random variables, in the context of nonextensive statistical mechanics. Applications for the consistency of estimators are presented and connections with stochastic processes are discussed.
