Reflected variance estimators for simulation
(Taylor & Francis Inc, 2015)
We propose a new class of estimators for the asymptotic variance parameter of a stationary simulation output process. The estimators are based on Standardized Time Series (STS) functionals that converge to Brownian bridges ...
Estimating the Parameters of the Generalized Lambda Distribution: Which Method Performs Best?
(Taylor & Francis Inc, 2016)
Generalized lambda distribution (GLD) is a flexible distribution that can represent a wide variety of distributional shapes. This property of the GLD has made it very popular in simulation input modeling in recent years, ...
Empirical distributions of daily equity index returns: A comparison
(Pergamon-Elsevier Science Ltd, 2016)
The normality assumption concerning the distribution of equity returns has long been challenged both empirically and theoretically. Alternative distributions have been proposed to better capture the characteristics of ...
Multiply reflected variance estimators for simulation
In a previous article, we studied a then-new class of standardized time series (STS) estimators for the asymptotic variance parameter of a stationary simulation output process. Those estimators invoke the well-known ...
