PSkewAA_fast: Piecewise Skewness Aggregate Approximation
In Jakob-Bach/FastTSDistances: Fast dissimilarity computations for time series
Description
Usage
Arguments
Details
Value

Description
Divides a time series into windowCount frames of equal length and
represents each interval by its skewness. If the time series length is not
divisible by the number of windows, one element might belong to two windows,
but only with a certain fraction to each.
Usage
1
PSkewAA_fast(x, windowCount, nanReplace = NA_real_)
Arguments
x
Numeric vector/time series.
windowCount
The number of windows for the shortened time series.
nanReplace
All NaN elements will be replaced with this value (default: NaN).
NaNs can occur if a segment is constant.
Details
The function is similar to PAA_fast, but simply uses a different
aggregate.
Value
A numeric vector of the length windowCount.

Other piecewise aggregation functions: PAA_fast,
PKurtAA_fast, PMaxAA_fast,
PMedAA_fast, PMinAA_fast,
