In this paper, we apply Markov chain techniques to select the best financial stocks listed on Ghana Stock Exchange based mean recurrent times and steady-state distribution for investment portfolio construction. Weekly stock prices from spanning January 2017 December 2020 was used study. A three-state estimate transition matrix, long-run probabilities, price movements one state another. Generall...

A commonly used defining property of long memory time series is the power law decay of the autocovariance function. Some alternative methods of deriving this property are considered working from the alternate definition in terms of a fractional pole in the spectrum at the origin. The methods considered involve the use of (i) Fourier transforms of generalized functions, (ii) asymptotic expansion...

Many of the world’s economies experienced rapid structural changes due to globalization and other forces over past 50 years. During this period, developing countries were recipients massive foreign direct investment, their industrialization was accompanied by urbanization, city gigantism, related environmental issues, such as pollution. Over time, investments in education urban poor allowed mov...

We present ASSA-PBN, a tool for approximate steady-state analysis of large probabilistic Boolean networks (PBNs). ASSA-PBN contains a constructor, a simulator, and an analyser which can approximately compute the steadystate probabilities of PBNs. For large PBNs, such approximate analysis is the only viable way to study their long-run behaviours. Experiments show that ASSAPBN can handle large PB...

In this paper a class of large supergames, i.e., infinitely repeated games played by many players are studied. The players located on the vertex set of planar rectangle lattice play several basic games with his neighbors. The basic game is two-person prisoners’ dilemma game with asymmetric payoffs. Under the conditions of the pre-specified updating rules and the transition probabilities, the re...
