Approximation Algorithms for Multi-index Transportation Problems with Decomposable Costs
The axial multi-index transportation problem is defined as follows. Given are k sets A,, each set having n, elements, r = 1,. , k. The Cartesian product of the sets A, is denoted by A. To each element a E A a certain cost, c, E R, is associated. Further, a nonnegative demand e,; is associated to each set Ari = {u E A : u(r) = i}. The problem is to find nonnegative real numbers x0 such that each...
متن کاملSignatures of Quantum-like Chaos in Dow Jones Index
Dow Jones Index time series exhibit irregular or fractal fluctuations on all time scales from days, months to years. The apparently irregular (nonlinear) fluctuations are selfsimilar as exhibited in inverse power law form for power spectra of temporal fluctuations. Inverse power law form for power spectra of fractal fluctuations in space or time is generic to all dynamical systems in nature and...
متن کاملPredictability of Dow Jones Index via Chaotic Symbolic Dynamics
We define alignment scores, the Hurst exponent and root mean square variation and use them along with Shannon entropy to analyze the Dow Jones index for the years 1985-2010. It is seen that the dynamical behavior of the US stock market is characterized by the temporal variations of the Hurst exponents, the Shannon entropy, the scores and the root mean square variation. We conclude that these me...
متن کاملThe role in index jumps and cojumps in forecasting stock index volatility: Evidence from the Dow Jones index
Modeling and forecasting realized volatility is of paramount importance. Previous studies have examined the role of both the continuous and jump components of volatility in forecasting. This paper considers how to use index level jumps and cojumps across index constituents for forecasting index level volatility. In combination with the magnitude of past index jumps, the intensity of both index ...
متن کاملComparative Research on Stock Volatility between Shanghai Composite Index and Dow Jones
Abstract:Accommodating exchange rate factors as exogenous disturbance, this paper proposes a mixed GARCH-Jump model to compares in general the volatility properties of returns series of the Shanghai composite index with those of the Dow Jones index. It also incorporates the asymmetry, clustering and leptokurtosis and fat-tail properties of returns volatility into an integrated analytic frame of...
