ClippedFT
class.The parameter type.boot
can be set to choose a block bootstrapping
procedure. If "none"
is chosen, a moving blocks bootstrap with
l=lenTS(Y)
and N=lenTS(Y)
would be done. Note that in that
case one would also chose B=0
which means that getPositions
would never be called. If B>0
then each bootstrap replication would
be the undisturbed time series.
clippedFT(
Y,
frequencies = 2 * pi/lenTS(Y) * 0:(lenTS(Y) - 1),
levels = 0.5,
isRankBased = TRUE,
B = 0,
l = 0,
type.boot = c("none", "mbb")
)
Returns an instance of ClippedFT
.
A matrix
of real numbers containing the time series from
which to determine the quantile periodogram as columns, or a
ts
object or a zoo
object.
A vector containing frequencies at which to determine the quantile periodogram.
A vector of length K
containing the levels at which the
ClippedFT
frequency representation is to be
determined.
If true the time series is first transformed to pseudo
data [cf. FreqRep
].
number of bootstrap replications
(expected) length of blocks
A flag to choose a method for the block bootstrap; currently
two options are implemented: "none"
and "mbb"
which means to do a moving blocks bootstrap with B
and l
as specified.
For an example see FreqRep
