Ordinary Clt and Wlln Versions of L =
نویسنده
چکیده
The familiar queueing principle expressed by the formula L=^\W (Little's law) can be interpreted as a relation among strong laws of large numbers (SLLNs). Here we prove central-limit-theorem (CLT) and weak-law-of-large-numbers (WLLN) versions of L = \W. For example, if the sequence of ordered pairs of interarrival times and waiting times is strictly stationary and satisfies a joint CLT, then the queue-length process also obeys a CLT with a related limiting distribution. In a previous paper we proved a functional-central-limit-theorem version oi L = \W, without stationarity, by very different arguments. The two papers highlight the differences between estabhshing ordinary limit theorems and their functional-limit-theorem counterparts.

A Central-Limit-Theorem Version of the Periodic Little’s Law
Abstract We establish a central-limit-theorem (CLT) version of the periodic Little’s law (PLL), which complements the sample-path and stationary versions of the PLL which we recently established in order to explain the remarkable accuracy in comparisons of data-generated model simulations to direct estimates from the data for the aggregate occupancy level in a hospital emergency department. Our...

متن کاملWeak Law of Large Numbers for Hybrid Variables Based on Chance Measure
Based upon previous studies on laws of large numbers for fuzzy, random, fuzzy random and random fuzzy variables, We go further to explore weak law of large numbers(WLLN) for hybrid variables comprising fuzzy random variables and random fuzzy variables. we mainly prove Chebyshev WLLN, Poisson WLLN, Bernoulli WLLN, Markov WLLN and Khintchin WLLN for hybrid variables based on chance measure.

Background & Aims: Methodology as a critical factor plays a significant role in achieving the acceptable results in educational fields, particularly in the process of language teaching and learning in applied linguistics. Analyzing the teaching methodology from different perspectives such as satisfaction is also important. Accordingly, the purpose of present paper is to evaluate the satisfactio...
متن کاملAlmost Sure Limit Theorems for the Pearson Statistic
Almost sure versions of limit theorems by Kruglov for the Pearson χ 2-statistic are obtained. 1. Introduction and preliminary results. Several papers are devoted to almost sure (a.s.) versions of central limit theorems (CLT), for a review see Berkes [1]. In this section we study a new version of the standard procedure (see Lacey and Philipp [5]) to prove an a.s. limit theorem. We use a strong l...
