An AR model of order 7 or 8 is required for Burg or Covariance method
and order 9 or 10 for Yule-Walker.
The Lerman and Yitzhaki covariance method
is employed to calculate Gini estimates; these estimates are more accurate than would have been possible with other methods, because microlevel, and not grouped, data are required.
It has been demonstrated that these approaches are capable of effectively seizing most useful information stored in the available data (e.g., the measurements based on eddy covariance method
), without depending on any complex underlying knowledge about the evolving process of ET.
Closed-Loop Linear Covariance Analysis introduces the analytical linear covariance method
to quantify the robustness measure for closed-loop relative trajectory dispersion.
On the basis of this principle, there are several main methods for detection of PBLH, such as gradient method, standard variance method, iterative curve-fitting method, and wavelet covariance method
