The Bayesian estimators for the unknown parameters of the bivariate Marshall–Olkin exponential distribution under noninformative priors have been considered and several reference priors have been derived. A class of priors is found by matching the coverage probability of one-side Bayesian...

In recent years, there have been quite a few attempts to apply intelligent techniques to financial trading, i.e., constructing automatic and intelligent trading framework based on historical stock price. Due to the unpredictable, uncertainty and volatile nature of financial market, researchers...

Using recently available night lights and electricity consumption data for the 212 municipios (counties) of Veracruz state in southern Mexico, the informal economy is analyzed at the Mexican county level for the first time with such data. Most counties between 2000 and 2006 are found to have...
