public abstract class AbstractTimeSeries extends Filter implements UnsupervisedFilter, OptionHandler
Valid filter-specific options are:
-R index1,index2-index4,...
Specify list of columns to calculate new values for.
First and last are valid indexes.
(default none)
-V
Invert matching sense (i.e. calculate for all non-specified columns)
-I num
The number of instances forward to merge values between.
A negative number indicates taking values from a past instance.
(default -1)
-M
For instances at the beginning or end of the dataset where the translated
values are not known, remove those instances (default is to use missing
values).
