The function extracts discrete wavelet transform coefficients from the raw
See wavelets::dwt for more information.
extractFDAWavelets(filter = "la8", boundary = "periodic")
Specifies which filter should be used.
Must be one of
c followed by an even
number for the level of the filter.
The level of the filter needs to be smaller or equal then the time-series length.
For more information and acceptable filters see
Boundary to be used.
“periodic” assumes circular time series,
for “reflection” the series is extended to twice its length.
Default is “periodic”.
