Forecast anomalies have been estimated by removing the mean model climate for the specific forecast period using only the predictions for which there are observational reference data available25.
Chemical alteration prevents accurate determination of the magnetization state beyond 600 °C, due to the difficulty of removing the mean inner potential contribution to the phase recorded from the new mineralization.
After removing the mean of those scratched frames, we add the residual to the test sequences.
We start with removing the mean value and a linear trend from the magnetic data.
Obviously, removing the mean from X will result in R replaced by covariance matrix ∑.
For a given quadrant, if, after removing the mean, the residue is greater than a prescribed threshold, the quadrant is further divided into four new quadrants.
For a given quadrant, if, after removing the mean, the residue is greater than a prescribed threshold (1 cm in our case), the quadrant is further divided into four new quadrants.
During data processing, we first made a baseline correction by removing the mean determined from a segment of the pre-event part of the original record from the entire original acceleration record.
