We propose a new approach to evaluating copula-based multivariate density forecasts. Employing Hansen’s SPA test and conducting multiple comparisons of fully-parametric models, our approach accommodates possible misspecifications in the multivariate joint and the univariate marginal...

We show that a straightforward modification of a trading based test for predictability displays interesting advantages over the Excess Profitability (EP) test (proposed by Anatolyev and Gerco) when testing the Martingale Difference Hypothesis. Our statistic is called Straightforward Excess...

This work aims to fill an existing gap in the literature regarding the statistical testing for the existence and the identification of the character of time-varying second moment in its dependence on a non-constant mean level in time series. To this end a new statistical testing procedure is...

This paper analyses the constant elasticity of volatility (CEV) model suggested by [6]. The CEV model without mean reversion is shown to be the inverse Box-Cox transformation of integrated processes asymptotically. It is demonstrated that the maximum likelihood estimator of the power parameter...
