'Expanded' SFA means that the input data are expanded into a higher-dimensional
space with the function sfaExpandFun. See sfaExpand
for the default
expansion function.
sfa2Create(
ppRange,
sfaRange,
ppType = "SFA1",
axType = "ORD1",
regCt = 0,
opts = NULL,
xpDimFun = xpDim,
sfaExpandFun = sfaExpand
)
umber of dimensions to be kept after preprocessing step - or - a two-number vector with lower and upper dimension number
umber of slowly-varying functions to be kept
preprocessing type: ="PCA", "PCA2" (principal component analysis) or ="SFA1" (linear sfa)
is the type of derivative approximation to be used, see sfaTimediff
regularization constant, currently not used
optional list of additional options
Function to calculate dimension of expanded data
Function to expand data
list sfaList
contains all arguments passed into sfa2create plus
evaluates to xpDimFun(ppRange)
