We investigated the relationship among inflation, output gap, and money in the time-frequency space for Malaysia over the period 1986:2-2008:12. We utilised the wavelet coherence and phase difference in continuous wavelet analysis and multiresolution in discrete wavelet analysis. We then...

This paper introduces and describes an alternative clustering approach based on the discrete wavelet transform (DWT) which satisfies requirements that other clustering methods, like discriminative-based clustering and model-based clustering approaches, do not satisfy. The clustering method has...
