This paper considers independently distributed stochastic processes that are also nonidentically distributed. We find that an identically distributed process with autocorrelations can be obtained from an independent, yet nonidentically distributed, random generator. Our approach is illustrated...

Given that financial series are poorly described by Gaussian distributions, how can the volatility behavior of such series be explained? Here we put forward a possible explanation to add the existing ones. We focus on a class of reduced variables that are independent and identically distributed....
