In this study, we examine the daily returns and daily range returns dependent on close–close and the high–low prices when forecasting multifractal volatility in the Chinese stock market. In in-sample forecasting we find that both the daily returns and range returns have a significant impact...

type="main" <title type="main">Summary</title> <p>Life cycle assessment (LCA) enables us to estimate potential resource and energy consumption as well as environmental emissions resulting from various activities within our economy. The present LCA intends to analyze the energy consumption and environmental emissions of the...</p>

A Kalman filter for application to stationary or non-stationary time series is proposed. A major feature is a new initialisation method to accommodate non-stationary time series. The filter works on time series with missing values at any point of time including the initialisation phase. It can...

A general Bayesian Markov Chain Monte Carlo methodology is utilized for conducting an analysis of the intensity process of stock market data. The sampling scheme employed is a hybrid of the Gibbs and Metropolis Hastings algorithms. Both duration and count data time series approaches are utilized...

This paper investigates the time caseworkers spend supporting long-term foster care and adoption placements. Undertaken in Australia through collaboration between university and non-government agency researchers, the 'Cost of Support Study' tracked the hours that caseworkers spent supporting...

An increase in correlation during turbulent market conditions implies a reduction in the benefits arising from portfolio diversification. Unfortunately, it is exactly then that these benefits are most needed. We investigate the robustness of recent empirical results that indicate correlation...

This paper investigates the dynamic behaviour of jumps in financial prices and volatility. The proposed model is based on a standard jump diffusion process for price and volatility augmented by a bivariate Hawkes process for the two jump components. The latter process speci.es a joint dynamic...
