Mean Absolute Deviations about the Mean, the Cut Norm and Taxicab Correspondence Analysis [PDF]

open access: diamondOpen Journal of Statistics, 2020
Optimization has two faces, minimization of a loss function or maximization of a gain function. We show that the mean absolute deviations about the mean, d, maximizes a gain function based on the power set of the individuals, and it is equal to twice the value of its cut-norm.

Mean-absolute deviation portfolio optimization model under transaction costs

open access: greenJournal of the Operations Research Society of Japan, 1999
Summary: We propose a branch-and-bound algorithm for solving a portfolio optimization model under nonconvex transaction costs. It is well known that the unit transaction cost is larger when the amount of transaction is small while it remains stable up to a certain point and then increases due to illiquidity effects.

The mean and median absolute deviations

open access: yesMathematical and Computer Modelling, 2001
The authors give a comprehensive survey of properties of mean and median absolute deviations of a distribution. Let \(X_1,X_2,\dots, X_n\) be independent and identically distributed random variables and \(\overline X_n\) be the sample mean. Let \(S^2_n= n^{-1} \sum^n_{i=1} (X_i- \overline X_n)^2\) and \(d_n= n^{-1} \sum^n_{i=1}|X_i-\overline X_n ...

Mean Absolute Deviation (About Mean) Metric for Kurtosis

open access: goldAdvance Research in Sciences (ARS)
In this paper, we introduce a MAD (about mean) alternative metric to classical kurtosis. Using the formula for mean absolute deviation, we identify two special points and construct the corresponding distributions with these reference points as their means. The proposed alternative is computed from mean absolute deviations for these distributions. These

Mean Absolute Deviation for Hyperexponential and Hypoexponential Distributions

open access: diamondOperations Research and Applications : An International Journal
Hyperexponential and Hypoexponential distributions are derived from mixtures and convolutions of independent exponential random variables, respectively, and have a wide range of applications in telecommunications, quantitative finance, and reliability analysis.

New Formulae and Uses of Mean Absolute Deviation [PDF]

open access: hybridInternational Journal of Business and Statistical Analysis, 2015
Mean absolute deviation about mean and median is extended to define "MAD-comoment" similarly analogous to classical central moment notation of covariance. Therefore, the "MAD-comoment" is used to derive the coefficient of determination in LAD regression, to analyze total sum of absolute into the pure between sum of absolute and the pure within sum of ...
