A Derivation of the Mean Absolute Distance in One-dimensional Random Walk
نویسنده
چکیده
In this paper we argue on the use of the mean absolute deviation in 1D random walk as opposed to the commonly accepted standard deviation. It presents an in detail derivation of the closed-form formula for the 1D mean absolute distance, including the proof by induction. The limit for the infinite number of steps is included.

A PRELUDE TO THE THEORY OF RANDOM WALKS IN RANDOM ENVIRONMENTS
A random walk on a lattice is one of the most fundamental models in probability theory. When the random walk is inhomogenous and its inhomogeniety comes from an ergodic stationary process, the walk is called a random walk in a random environment (RWRE). The basic questions such as the law of large numbers (LLN), the central limit theorem (CLT), and the large deviation principle (LDP) are ...
متن کاملApproximation and Analytical Studies of Inter-clustering Performances of Space-Filling Curves
A discrete space-filling curve provides a linear traversal/indexing of a multi-dimensional grid space. This paper presents an application of random walk to the study of inter-clustering of space-filling curves and an analytical study on the inter-clustering performances of 2-dimensional Hilbert and z-order curve families. Two underlying measures are employed: the mean inter-cluster distance ove...

متن کاملLong Memory in Stock Returns: A Study of Emerging Markets
The present study aimed at investigating the existence of long memory properties in ten emerging stock markets across the globe. When return series exhibit long memory, it indicates that observed returns are not independent over time. If returns are not independent, past returns can help predict future returns, thereby violating the market efficiency hypothesis. It poses a serious challenge to ...
