The linear linearWeight and logisticWeight weight functions
can be passed to twdtwApply through the argument weight.fun.
This will add a time-weight to the dynamic time warping analysis. The time weight
creates a global constraint useful to analyze time series with phenological cycles
of vegetation that are usually bound to seasons. In previous studies by
Maus:2016;textualdtwSat the logistic weight had better results than the
linear for land cover classification. See Maus:2016;textualdtwSat and
Maus:2019;textualdtwSat.
