This paper compares the short-term load performance of several forecasting models, including a new class of nonlinear models known as smooth transition periodic autoregressive (STPAR) models. A model building procedure is developed for the STPAR model, along with a linearity test against smooth...

In electrical power systems with strong hydro generation, the use of adequate techniques to generate synthetic hydrological scenarios is extremely important for the evaluation of the ways the system behaves in order to meet the forecast energy demand. This paper proposes a new model to generate...

The objective of this study was to analyse the changes in the intraday market microstructure behaviour before a takeover announcement for a sample of target, bidder and control (non-target) companies. Under the hypothesis that agents with asymmetric information were operating in the market, the...

In this paper, it is shown how one can employ the wavelet analysis to reconstruct data based only on the subset of information that differentiates the two fundamentally related time series: spot and futures indices. Such an analysis allows researchers to focus on examining the relationship...

Previous studies provide conflicting evidence on the time series properties of company financial ratios, claiming either that the components of ratios exhibit nonstationarity which is not eliminated by the ratio transformation, or that a unit root in the components may be rejected which implies...

This study develops a method to select variables, and to specify the relative importance of those variables, as input for failure models. In addition, our method provides estimates of the failure probabilities of organisations at a point in time. The results of tests of our method on Australian...
