Global approach estimates missing values based on global correlation information extracted from the entire data matrix [ 12].
Subsequently, we investigated whether the changes in sense and antisense transcript levels between times points are correlated and observed no global correlation (Additional file 5: Figure S3).
Global correlation is based on 121/2 conodont biozones for the complete Silurian.
"What has happened is that the sectors with the highest global correlation that is, technology and telecommunications -- now represent more and more of the stocks in the index".
The ammonites of this age worldwide exhibit a high level of regional differentiation, making global correlation difficult.
This regional isolation of many faunas contributed to the intense pace of the Ordovician radiation, but it has also made the global correlation of Ordovician rocks difficult.
The International Commission on Stratigraphy (ICS) formed several working groups to define new stages based on a more accurate global correlation of stratigraphic and fossil markers.
Many of these units may have formed from changes in global sea level and may ultimately be useful for global correlation.
The study strongly supports the approach of developing a local correlation versus a global correlation.
The global correlation of radial vorticity and tangential divergence is again high.
Finally, an anomaly is detected by a global correlation coefficient of anomalous space.
