|Abstract: ||The daily closing prices of several stock market indices are examined to analyse whether
noise reduction matters in measuring dependencies of the financial series. We consider
the effect of noise reduction on the linear and nonlinear measure of dependencies. We
also use singular spectrum analysis as a powerful method for filtering financial series.
We compare the results with those obtained by ARMA and GARCH models as linear and
nonlinear methods for filtering the series. We also examine the findings on an artificial
data set namely the Hénon map.|
