MODELING WITH THE CHAOS GAME (II). A CRITERION TO DEFINE THE RELEVANT TRANSITION PERIODS IN ROMANIA

Lucrarea prezintă o metodă de partiţionare a perioadelor relevante pentru tranziţia sistemului economic românesc din ultimii 20 de ani, reflectată in cursul de schimb leu-dolar american. Extinzând rezultatul unei lucrari anterioare, metoda ia in considerare evoluţia in timp a valorilor cuartilelor si masura in care sub-seriile reale pot genera structuri fractale auto-replicante “Sierpinski gasket” prin procedeul iterativ de tip “Chaos Game”. Metoda are corespondent in istoria reală a evenimentelor. The paper is focusing on a new partition method of the transition epoque suffered by the Romanian economic system in the last two decades as revealed by the Romanian Leu-United States Dollar exchange rate time series. By extending the results of a previous work, the method is considering the time evolution of the quartiles and the extent to what the real sub-series could generate the fractal selfsimilar structure “Sierpinski gasket” by using the iterative procedure of Chaos Game type. The method is supported by the historical evolution of the events.
