Wavelets and prediction in time series

Mošová, Vratislava

Similarity:

Wavelets (see [2, 3, 4]) are a recent mathematical tool that is applied in signal processing, numerical mathematics and statistics. The wavelet transform allows to follow data in the frequency as well as time domain, to compute efficiently the wavelet coefficients using fast algorithm, to separate approximations from details. Due to these properties, the wavelet transform is suitable for analyzing and forecasting in time series. In this paper, Box-Jenkins models (see [1, 5]) combined...

A general Approach to Methods with a Sparse Jacobian for Solving Nonlinear Systems of Equations

Kyurkchiev, Nikolay, Iliev, Anton (2007)

Serdica Mathematical Journal

Similarity:

2000 Mathematics Subject Classification: 65H10. Here we give methodological survey of contemporary methods for solving nonlinear systems of equations in Rn. The reason of this review is that many authors in present days rediscovered such classical methods. In particular, we consider Newton’s-type algorithms with sparse Jacobian. Method for which the inverse matrix of the Jacobian is replaced by the inverse matrix of the Vandermondian is proposed. A number of illustrative numerical...
