, with the use of an alternative to the standard principal components approach – independent components analysis (ICA). ICA … seeks higher moment independence and maximises in relation to a chosen risk parameter. We apply an ICA based on kurtosis … maximisation to weekly US REIT data using a kurtosis maximising algorithm. The results show that ICA is successful in capturing the …

A new model class for univariate asset returns is proposed which involves the use of mixtures of stable Paretian distributions, and readily lends itself to use in a multivariate context for portfolio selection. The model nests numerous ones currently in use, and is shown to outperform all its...

In this paper, we apply independent component analysis (ICA) for prediction and signal extraction in multivariate time … series data. We compare the performance of three different ICA procedures, JADE, SOBI, and FOTBI that estimate the components … performance of those three ICA procedures on capturing the dynamic relationships among the industrial production index (IPI) time …
