Correlations between many elements in a system inevitably contain indirect correlations from other elements.
You should also be very careful when you calculate a correlation between Time series.

Handling indirect correlation #
The indirect correlation leads us to inaccurate prediction. There are several ways to filter out those indirect edges with spurious correlation:
 Correlation of correlations
 Partial correlation
 Mutual information based approach (citation needed).

 Network link prediction by global silencing of indirect correlations
Aggregating correlation #
Sometimes, we want to average correlation values. A standard method is performing Fisher transformation and average the z values then transform it back to correlation coefficient.
