Description Usage Arguments Value Author(s) References See Also Examples
The function automatically applies an empirical mode decomposition to a
provided univariate time series. Wrapper function for emd
of the Rlibeemd
package. It also allows the automatic selection
of meaningful IMFs using fittestEMD
.
emd.rev()
reverses the transformation.

pred |
A list containing IMFs produced by empirical mode decomposition. |
A list containing the meaningful IMFs of the empirical mode decomposition of x
.
A vector indicating the indices of the meaningful IMFs and the number of IMFs produced are passed as attributes
named "meaningfulImfs" and "num_imfs", respectively.
