Wavelet timescales and conditional relationship between higher order systematic co-moments and portfolio returns: evidence in Australian data

2004

Don U.A. Galagedera Elizabeth A. Maharaj

This paper investigates association between portfolio returns and higher-order systematic co-moments at different timescales obtained through wavelet multiscalinga technique that decomposes a given return series into different timescales enabling investigation at different return intervals. For some portfolios, the relative risk positions indicated by systematic co-moments at higher timescales ...

BACKGROUND AND PURPOSE Texture analysis is an image processing technique that can be used to extract parameters able to describe meaningful features of an image or ROI. Texture analysis based on the gray level co-occurrence matrix gives a second-order statistical description of the image or ROI. In this work, the co-occurrence matrix texture approach was used to extract information from brain M...
