This revealed that the temporal correlations within the data are a more significant source of the multi-fractal scaling than the distribution of the financial returns.

«This is a very important finding,» says Prof. March Ernst, «not just because it shows that the brain uses the temporal correlation of sound and light to detect whether or not they are physically related, but also because it opens an even more intriguing question: how does the brain detect correlation across the senses?»

Recently, functional network connectivity (FNC, defined as the temporal correlation among spatially distant brain networks) has been used to examine the functional organization of brain networks in

Resolving the numerous methodological differences and criticisms of proxy reconstruction is beyond the scope of this chapter, but we will address some key issues related to temporal correlation, the use of principal components, and the interpretation of validation statistics.

Using the statistical structure of temporal correlations in fluctuations for generated and forecast power time series, we quantify two types of forecast error: a timescale error (eτ) that quantifies deviations between the high frequency components of the forecast and generated time series, and a scaling error (eζ) that quantifies the degree to which the models fail to predict temporal correlations in the fluctuations for generated power.
