The integration of fuzzy logic systems and neural networks in data driven nonlinear modeling applications has generally been limited to functions based upon the multiplicative fuzzy implication rule for theoretical and computational reasons. We derive a universal approximation result for the...

As a contribution toward the ongoing discussion about the use and mis-use of p-values, numerical examples are presented demonstrating that a p-value can, as a practical matter, give you a really different answer than the one that you want.

This paper models the stochastic behavior of large-scale terrorist events using extreme value methods. We utilize a unique dataset composed of roughly 24,000 observations. These data provide a rich description of domestic and international terrorism between 1968 and 2005. Currently a credible...

Value-at-Risk (VaR) has been widely promoted by the Bank for International Settlement (BIS) as well as central banks of all countries as a way of monitoring and managing market risk and as a basis for setting regulatory minimum capital standards. The revised Basle Accord, implemented in January...

The random walk hypothesis is rejected for foreign stock market prices. Variance ratio tests are performed on weekly stock prices of nine major foreign stock market indices. While longer-term returns follow random walks, short-horizon, bi-weekly returns exhibit significant positive serial...

Expectile regression produces the best linear unbiased estimator for regression lines other than the mean regression in model designs with asymmetric conditional variance of the error term. In some cases where OLS assumptions are violated, an expectile regression estimator is also the BLUE for...

In today’s technology-driven world-economy, banking-services have been modernized where customers compete for comparative time-saving-options. Bangladesh, a developing country, is no exception. Besides traditional banking, Agent-banking, bKash, Western-Union etc. serve new-way...

This paper aims to determine which extreme value copula is best suited to the bivariate relationships between shocks of U.S market with Brazilian, Argentine and Mexican markets. We used prices of S&P500, Ibovespa, Merval and IPC from January, 3, 2009 to December, 31, 2010, totaling 483...
