spilloverFft

This function is an internal implementation of the frequency spillover.
We apply the identification scheme suggested by fevd to the frequency
decomposition of the transfer functions from the estimate est.

Accompanies a paper (Barunik, Krehlik (2018) <doi:10.1093/jjfinec/nby001>) dedicated to spectral decomposition of connectedness measures and their interpretation. We implement all the developed estimators as well as the historical counterparts. For more information, see the help or GitHub page (<https://github.com/tomaskrehlik/frequencyConnectedness>) for relevant information.
