We fit the normal inverse Gaussian(NIG) distribution to foreign exchange closing prices using the open software package R and select best models by Kaarik and Umbleja (2011) proposed strategy. We observe that daily closing prices(12/04/2008 - 07/08/2012) of CHF/JPY, AUD/JPY, GBP/JPY, NZD/USD,...

While the Generalized Error Distribution (GED) has been used quite extensively in time series applications and has demonstrated a sound flexibility in the estimation process, there is so far no attempt to use this function in the construction of Copulas. Copulas are probability functions that...

The central banks introduce and implement the monetary and financial stabilities policies, going from the accurate estimations of national macro-financial indicators such as the Gross Domestic Product (GDP). Analyzing the dependence of the GDP on the time, the central banks accurately estimate...

In this paper we have found an analytical formula for a copula that connects the numbers Ni of customers in the nodes of a Gordon and Newell queueing network. We have considered two cases: the first one is the case of the network with 2 nodes, and the second one is the case of the network with...
