A dynamic hybrid model based on wavelets and fuzzy regression for time series estimation
Financial time series Wavelet decomposition Fuzzy regression SP500 index
2011/3/23
In the present paper, a fuzzy logic based method is combined with wavelet decomposition to develop a step-by-step dynamic hybrid model for the estimation of financial time series. Empirical tests on f...
An Empirical Test of the Athens Exchange New-Sector Indices Predictability Based on Wavelets
Time series forecasting stock market prediction
2010/9/7
A new forecasting method is employed using Haar and Daubechies-4 filters. Backtesting results, using four indices of the Athens Exchange (ATHEX), are benchmarked against an optimised Auto-Regressive ...
Haar Wavelets-Based Approach for Quantifying Credit Portfolio Losses
Haar Wavelets-Based Quantifying Credit Portfolio Losses
2010/11/1
This paper proposes a new methodology to compute Value at Risk (VaR) for quan-tifying losses in credit portfolios. We approximate the cumulative distribution of the loss function by a nite combinatio...
