Abstract
In the last twenty years, the copulas gained a considerable importance in investigating the dependence structure between two or more random variables. Therefore the number of researches on the mathematical and statistical properties of copulas increases from year to year, and hence the application area for copulas becomes so widespread in the same direction. In this study, some extensions of FGM family, proposed by Huang and Kotz (1999) and Lai and Xie (2000) are examined on the Turkish Lira basis of changes in American Dollar and gold prices.
